Answer:
b = -3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6b+14=−7−b
6b+14=−7+−b
6b+14=−b−7
Step 2: Add b to both sides.
6b+14+b=−b−7+b
7b+14=−7
Step 3: Subtract 14 from both sides.
7b+14−14=−7−14
7b=−21
Step 4: Divide both sides by 7.
[tex]\frac{7b}{7} = \frac{-21}{7}[/tex]
b= -3
Answer:
b=−3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6b+14=−7−b
6b+14=−7+−b
6b+14=−b−7
Step 2: Add b to both sides.
6b+14+b=−b−7+b
7b+14=−7
Step 3: Subtract 14 from both sides.
7b+14−14=−7−14
7b=−21
Step 4: Divide both sides by 7.
7b

Ajar contains 6 pennies, 14 nickels, 16 dimes and 4 quarters. If one coin is
chosen at random, find P(nickel or dime) as a simplified fraction. You may
use the standard keyboard or Equatio to type the fraction. *
Answer:
P(nickel or dime) = 3/4
Step-by-step explanation:
First, find the total amount of coins that there are:
6 + 14 + 16 + 4 = (20) + (20) = 40
You are trying to find P(nickel or dime). Note that there are 14 nickels, and 16 dimes. Add these two numbers together:
P(Nickel or dime) = (14 + 16)/40
P(Nickel or dime) = (30)/40
Simplify. Divide common factors from both the numerator & denominator (10)
P(Nickel or dime) = (30/40)/(10/10) = 3/4
P(nickel or dime) = 3/4

Sally identified the terms of the expression 9a + 4b - 18 as 9, 4, and 18. Explain her error.
A term is a single mathematical expression. It may be a single number (positive or negative), a single variable (a letter), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.
So the terms are 9a, 4b, and 18.
hope it helps!
Answer:
Step-by-step explanation:
For the terms of the expression , Sally has to write coefficients with the variables
Terms: 9a , 4b , - 18
coefficient of b is = 1
Coefficient of a term is the numerical value of the variable

y= -3X + 8
y= -5x - 2
Answer:y=-5x-2
Step-by-step explanation:
Answer:
x=5 y= -7
Step-by-step explanation:
y= -3x +8
-(y= -5x -2)
=> y=-3x+8
-y=5x+2
=> 0=2x+10
=> x=5
=>y=-3(5)+8
=> y= -7

Is it possible to draw a triangle with these measurements?
• Side lengths 2 cm, 3 cm, and 4 cm
Answer:
Yes
Step-by-step explanation:
To form a triangle, any 2 of the side lengths added together must be greater than the 3rd side. In this case 2cm + 3cm = 5cm which is greater than 4cm (the remaining side)

the price of a shirt is increased by 10%. later the price is reduced in a sale by 10%, is the sale price more, less or the same as it was at the start? give reasons for your answer
Answer:
less
Step-by-step explanation:
We assume price of a shirt is $100.
Initially price is increased by 10%: 100+10=110
Then it is reduced by 10%: 110-11=99
Now price of a shirt is $99.
Answer is price of a shirt is less than it was at the start.

What is a set of numbers are intergers but not whole numbers or natural numbers?
If you have negative numbers anywhere in the set, then that set cannot be part of the whole numbers or natural numbers. This is because
set of whole numbers = {0,1,2,3,4,5,...}
set of natural numbers = {1,2,3,4,5,...}
The only difference is that 0 is not included in the set of natural numbers. Neither set has negative values in them.
So for instance the set {-5, 1,2,7} involves a number that is neither part of the whole numbers or natural numbers set. But every item listed is an integer
set of integers = { ..., -3, -2, -1, 0, 1, 2, 3, ... }
We can see that the integers is the set of positive and negative whole numbers, with 0 as well
Answer:
All whole numbers are integers (and all natural numbers are integers), but not all integers are whole numbers or natural numbers. For example, -5 is an integer but not a whole number or a natural number.
Step-by-step explanation:
Juvi is baking oatmeal raisin cookies and fudge brownies! To make 4 batches of brownies, Juvi needs 2/3 of a cup of sugar. She already has 1/2 of a cup of sugar in her cabinet and her sister Evi brings her 2/5 of a cup of sugar when she hears she needs more! Will Juvi have enough sugar to make 4 batches of brownies? If she does not have enough, how much more does she need? Explain below.**PLEAE HELP WILL MARK BRAINLIEST.
We can add the fractions together to compare with how much sugar she needs.
[tex]\frac{1}{2}+\frac{2}{5}=\frac{5}{10}+\frac{4}{5}=\frac{9}{10}[/tex]
So Juvi has [tex]\frac{9}{10}[/tex] cups of sugar.
She needs [tex]\frac{2}{3}[/tex] cups, so let's make the denominators the same and compare.
[tex]\frac{2}{3}=\frac{20}{30}[/tex]
[tex]\frac{9}{10}=\frac{27}{30}[/tex]
Since [tex]\frac{27}{30}[/tex] > [tex]\frac{20}{30}[/tex], she has enough sugar to make 4 batches of brownies.
Hope this helps.

Jayden deposited $13 in a savings account that earns 2.6% simple interest. Which graph represents this scenario?
Answer:
not a hundred percent sure since there are no graphs attached but mine was Graph 1 to be the answer
After 2 years she will have earned $12 * 2*2.3% = $12* 4.6% = 55c interest (to the nearest cent). Therefore the balance will be $12.55
After 6 years she will have earned $12 * 6*2.3% = $12* 13.8% = $1.66 interest (to the nearest cent).
Therefore the balance will be $13.66
After 10 years she will have earned $12 * 10*2.3% = $12* 23% = $2.76 interest (to the nearest cent).
Therefore the balance will be $14.76

simplify 4+3(7+4 x 2)-100
Answer:
- 51
Step-by-step explanation:
Order of operations. What's in the parenthesis is first.
4 + 3 ( 7+4 x 2) - 100
Concentrate on (7 + 4 x 2 ) first.
We multiply first so 4 x 2 = 8 then we add.
(7 + 8) = 15
4 + 3(15) - 100 Again, we multiply first.
4 + 45 - 100 Now we can add and subtract in any order.
49 - 100 = - 51
what must be added to ‐213 to get ‐312

(9h+3)(−h−1) porfavor ayudenme con esta pregunta.
Answer:
-9h² - 12h - 3
Step-by-step explanation:
Follow the FOIL method:
FOIL = First, Outside, Inside, Last
Multiply the terms together:
First: 9h * -h = -9h²
Outside: 9h * -1 = -9h
Inside: 3 * -h = -3h
Last: 3 * -1 = -3
Combine like terms: 9h² + (-9h - 3h) - 3
9h² - 12h - 3
-9h² - 12h - 3 is your answer.
