Answer: $500

Step-by-step explanation:

Let the number be y

15% of y = 75

15/100 × y = 75

15y/100 = 75

Cross multiply

15y = 75 × 100

15y = 7500

y = 7500/15

y = 500.

\text{In this question, you would need to find the right value that 15\% is \$75}\\\\\text{You can do this by multiplying each number by 0.15}:\\\\200*0.15=30\\\\300*0.15=45\\\\350*0.15= 52.5\\\\500*0.15=75\\\\\text{You would see that 15\% of 500 is \$75}\\\\\boxed{\$500}

Answer:

\boxed{\sf d. \ \frac{a}{b}  =  \frac{10}{7}}

Step-by-step explanation:

\sf \implies \dfrac{a - b}{b}  =  \dfrac{3}{7}  \\  \\  \sf \implies  \frac{a}{b}  -  \frac{b}{b}  =  \frac{3}{7}  \\  \\  \sf \implies  \frac{a}{b}  - 1 =  \frac{3}{7}  \\  \\  \sf \implies  \frac{a}{b}  - 1 + 1 =  \frac{3}{7}  + 1 \\  \\  \sf \implies  \frac{a}{b}  =  \frac{3}{7}  + 1 \\  \\  \sf \implies  \frac{a}{b}  =  \frac{3}{7}  +  \frac{7}{7}  \\  \\  \sf \implies  \frac{a}{b}  =  \frac{3 + 7}{7}  \\  \\  \sf \implies  \frac{a}{b}  =  \frac{10}{7}

How to solve linear equations using graphs
Artemon [7]

Explanation:

We usually use graphs to solve two linear equations in two unknowns.

The basic idea is that a graph of an equation is the pictorial representation of all of the points that satisfy the equation. So, where the graph of one equation crosses the graph of another, the point where they cross will satisfy both equations.

Finding a solution means finding values of the variables that satisfy all of the equations. Hence, the point of intersection is the solution of the equations.

__

To solve linear equations by graphing, graph each of the equations. Then find the coordinates of the point where the lines intersect. Those coordinates are the solution to the equations.

If the solution is not at a grid point on the graph, determining its exact value may not be easy. This can often be aided by a graphing calculator, which can often tell you the point of intersection to calculator accuracy.

__

If the lines don't intersect, there are no solutions. If they are the same line (intersect everywhere), then there are an infinite number of solutions.

Who can help me with this
Lady bird [3.3K]

Answer:

Growth

Step-by-step explanation:

Given

\frac{2}{3}(2.5)^x

Required

Growth or decay

The general form is:

y = ab^x

Such that:

b = rate

For b, we have the following conditions:

b > 1 ----- Growth

0 --- Decay

b = 1 ---- None

Compare \frac{2}{3}(2.5)^x to y = ab^x

b = 2.5

<em>Because 2.5 > 1, then the first condition applies (growth)</em>
