What is the first step needed to solve 4 over 7 multiplied by x minus 5 equals negative 13? Subtract 13 from both sides Divide both sides by 7 Add 5 to both sides Multiply both sides by 4

Answers

Answer: C) add 5 to both sides

The given equation is

(4/7)x - 5 = -13

To solve this, we follow PEMDAS in reverse undoing each operation. Normally parenthesis is the first thing we look for, but instead we start with subtraction.

So we'll undo subtraction which means we add 5 to both sides

Problem:

Craig earns extra money as a lifeguard. He earns $37 for 4 hours and $64.75 for 7 hours.

Answers

Answer:

The answer is: y = 9.25x

Step-by-step explanation:

Let the equation for the proportionality relation is y = mx .......... (1), where y represents the money that Craig earns for a duty of x hours.

Here, m is the constant of proportionality and we have to find its value.

Given that Craig earns $37 for 4 hours duty.

So, from equation (1), we have 37 = 4m, ⇒ m = 9.25

Therefore, the equation becomes y = 9.25x. (Answer)

In a sixth grade class the ratio of boys to girls is 4:3 if there are 35 students in the class how many girls are there

Answers

Answer:

The given ratio is 3:4 this means there are 7 people in each unit of this ratio.

It is stated that there are 35 students in total . That would mean that there are

5 Total sets of students in this class . When we multiply the numbers in our starting ratio by this multiple of 5 , our ratio now becomes 15 : 20

15 and 20 do indeed add up to 35 … But , our question wants to know how many more GIRLS are in the class . Boys were calculated to be 15 in number .

Girls were calculated to be 20 in number .

We now know there were 5 more girls than boys in that class ..

5 is your answer .

Answered January 9, 2020

total number of student in class=35

let the number of boys be 3x

let the number of girls be 4x

so therefore 3x+4x=35 =>7x=35 =>x=5

so therefore number of boys in class is 3x=>3(5)=15

and number of girls in class is 4x=>4(5)=20

so there are 20–15=5 more girls in class than boys.

Let the number boys in the class be b. So b/(35-b)=3:4, or 105-3b=4b, or 7b=105, or b=15. The number of girls in the class is 35-15=20 20-15=5

Ans: there are 5 more girls than the number of boys in the class.

Tell whether the angles are complementary or supplementary. Then find the value of x

Answers

Answer:

Complementary, x=78

Step-by-step explanation:

90= (x-8)+20

complementary angles add up to 90 degrees.

Answer:

Complementary, x is 78

Step-by-step explanation:

Let's first define what complementary and supplementary angles are. Complementary angles add up to 90 degrees, and supplementary add up to 180. From this image, we can see that this is a right angle. Right angles add up to 90 degrees, therefore, this is a complementary angle.

Now, because we know that it is 90 degrees and that (x-8)+(20) = 90, then we can solve for x. However, if the angle is unknown, then we would do x-8=20. In this case, sense we know for sure this angle is complementary, we do

(x-8)+(20) = 90

X+12=90 We combined like terms

X=78 Inverse operations

You can plug 78 into x and check to see if it is correct if they are 90 degrees total.

Find the measure of the missing angle

Answers

The line is straight, so the 2 angles have to equal 180. Since we already know one angle is 21 degrees, we can subtract that from 180 to find the measure of the second angle. 180-21=159
So the measure of the other angle is 159 degrees.

Answers

Answer:

below in bold

Step-by-step explanation:

f(x) = 2x - 7 - 3

~Combine like terms

f(x) = 2x - 10

When x = 2...

f(x) = 2(2) - 10

f(x) = 4 - 10

f(x) = -6

When x = 3...

f(x) = 2(3) - 10

f(x) = 6 - 10

f(x) = -4

When x = 4...

f(x) = 2(4) - 10

f(x) = 8 - 10

f(x) = -2
