Step-by-step explanation:
1. Find (4y - 5)(3) - 7).
Last year, Andrea ran about 120 kilometers during the months of March, April, and May. Estimate how many more kilometers she ran during those three months than she ran this year. Round to the nearest 1 kilometer. A 2-column table with 3 rows titled Total Distance Andrea Ran (kilometers). Column 1 has entries March, April, May. Column 2 has entries 48.7, 31.2, 35.66.
Answer:
March=49
April=31
May=36
Andrea ran about 116 km
this is about 4 km less than last year
Step-by-step explanation:
I got it right :))
Andrea ran 4 km extra last year if, and the total distance run this year is 120 km, The distance ran in this year's March, April, and May = 48.7, 31.2, and 35.66.
What is subtraction?The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.
Given:
Total distance run this year = 120 km,
The distance ran in this year's March, April, and May = 48.7, 31.2, and 35.66.
Calculate the total distance = 48.7 + 31.2 + 35.66
The total distance this year = 115.56 or 116 km
Calculate the difference as shown below,
Distance = 120 - 116 = 4 km,
Thus, she ran 4 km extra last year.

A leg of a right triangle measures 12 cm. The hypotenuse of the triangle measures 37 cm. What is the measure, in centimeters of the other
leg of the triangle?
25
35
39
49
Answer:
The answer is 35Step-by-step explanation:
Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side b
Using Pythagoras theorem we have
a² = b² + c²
where a is the hypotenuse
Substitute the values into the above formula and solve
That's
[tex] {37}^{2} = {b}^{2} + {12}^{2} \\ {b}^{2} = {37}^{2} - {12}^{2} \\ { b}^{2} = 1369 - 144 \\ {b}^{2} = 1225 \\ b = \sqrt{1225} [/tex]We have the final answer as
35Hope this helps you
Answer:
35
Step-by-step explanation:
To solve for the hypotenuse of a right triangle, we use the Pythagorean Theorem, which is an equation to solve for the length of the hypotenuse given the two sides. The equation is a^2+b^2=c^2, where A and B are the legs of the triangle, and C is the hypotenuse. Let's manipulate this equation now. We are given one leg and the hypotenuse length, so the equation would be 12^2+b^2=37^2. Since we are trying to find the length of one of the legs, you subtract 12^2 from 37^2 to isolate B, and you get B^2 as 1225. You take the square root of both sides, and then you get 35 as the answer.

-4c+25+c=3c+79
Answer:
c = -9
Step-by-step explanation:
- 4c + 25 + c = 3c + 79 Combine like terms.
- 4c + c + 25 = 3c + 79
- 3c + 25 = 3c + 79
- 3c + 3c + 25 = 3c + 3c + 79
25 = 6c + 79
25 - 79 = 6c + 79 - 79
- 54 = 6c
-54/6 = 6c/6
-54/6 = c
-9 = c
There aren't 2 answers, you could have 2 answers if one of the c's was squared. Here is another way to do the math.
- 4c + 25 + c = 3c + 79
- 4c + c + 25 = 3c + 79
- 3c + 25 = 3c + 79
- 3c - 3c + 25 = 3c - 3c + 79
- 6c + 25 = 79
- 6c + 25 - 25 = 79 - 25
- 6c = 54
- 6c/- 6 = 54/- 6
c = 54/- 6
c = - 9
Answer:
-9 = c
Step-by-step explanation:
-4c+25+c=3c+79
-3c +25 =3c+79
25 = 6c +79
-54=6c
-54/6 = c
-9 = c

Use distributive property.
First distribute the 3x
3x times x^2 + 6x + 9. Distribute = 3x^3 + 18x^ 2 + 27x
Now we distribute the -1
-1 times x^2 + 6x + 9. Distribute = -x^2 -6x - 9

The ratio of boys to girls in a class is 5:7. There are 36 students in the
class. How many students are boys?
Answer:
15
Step-by-step explanation:
The ratio has been simplified so it may be hard to read.
To fix this multiply both the 5 and 7 by 3
This will give you 15:21
15 + 21 = 36 which is the total number of students.
Keeping the ratio in the same order means that there are 15 boys.
Answer:
There are 15 boys in the class.
Step-by-step explanation:
There are several ways to solve this, but here's how I did it:
5 (boys) : 7 (girls) = 12 students. There are 26 students, so we need to multiply this by 3.
15 (boys) : 21 (girls) = 36 students.
