1.
Since 5x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 5x from both sides.
3x−7−5x=13

Add 3x and −5x to get −2x.
−2x−7=13

Move -7 to the right hand side of the equation.
−2x=7+13

Add 7 and 13 to get 20.
−2x=20

Divide each term in the equation by −2.

x=−10

2.
Since 5x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 5x from both sides.
7−3x−5x=13

Add −3x and −5x to get −8x.
7−8x=13

Move 7 to the right hand side of the equation.
−8x=−7+13

Add −7 and 13 to get 6.
−8x=6

Divide each term in the equation by −8.

x=−3/4

First you need to combine like terms
7-3x= 5x+13
step 1 add 3x
7=8x+13
step 2 subteact 13
-6=8x
step 3 divide both sides by two
x=-3/4

A group of biologists found a total of 15 loggerhead turtle nests along a beach during a certain season. This was 20% of the tot

Andre45 [30]

20% also equals 1/5, right?

So in order to find the total number of turtle nests, just find 5/5, or multiply 15 by 5.

15 x 5 = 75

There were 75 total nests

Jonathon and Raymond earn a base salary plus commission. Jonathon earns $1500 plus 10% of his sales each month. Raymond earns $1

joja [24]

Answer:

The Jonathon and Raymond need to sell 6000 sales to earn the same amount each month.

Step-by-step explanation:

Given data

Let no. of sales = x

Jonathon earning = $ 1500 + $\frac{10}{100} x$

Raymond earning = $ 1200 + $\frac{15}{100} x$

Given that the earnings of Jonathon & Raymond are same.

1500 + $\frac{10}{100} x$ = 1200 + $\frac{15}{100} x$

300 = $\frac{5}{100} x$

x = 6000 sales

Therefore the Jonathon and Raymond need to sell 6000 sales to earn the same amount each month.

11) In a triangle, the ratio of the measures of three angles is 2:5:8. Find the measures of

natta225 [31]

Answer:

Sum of interior angles of a triangle always = 180 degrees

add the individual ratios to get a sum composite ratio:

2+5+8 = 15

180 / 15 = 12

Multiply individual ratios:

{2:5:8} * 12 = 24:60:96

Check:

24 + 60 + 96 = 180

Step-by-step explanation:

I hope it's help

Which of the following equations models the relationship of angle A to the length of the line segment BC in the figure below.

Anastasy [175]

Let the line segment BD be x, then sin A = x/15
or, x = 15sinA
Also $y^{2} = x^{2} + (25)^{2} \\ = (15sinA)^{2} + 625 \\ =225 sin^{2} A+625 \\ y= \sqrt{225 sin^{2} A+625} 
$
The last option
