I would like to know what 0.5-0.125q=(q-1)/4 equals out to.
Scrat [10]

Answer:

q = 2

Step-by-step explanation:

0.5-0.125q=(q-1)/4

At first, we have to multiply both the sides by 4.

4 × (0.5 - 0.125q) = q - 1

or, 2 - 0.5q = q - 1

now, we change the side by taking constant into the right side and the number into the left side.

2 + 1 = q + 0.5q

or, 3 = q (1 + 0.5)

or, 3 = 1.5 q

or, 1.5 q = 3

or, \frac{1.5q}{1.5} = (3 ÷ 1.5) [Dividing both the sides by 1.5]

or, q = 2

Therefore, q = 2

Kyra was at soccer practice. she blocked 55% of the goals that were kicked at her during a team drill. ashley scored two of the
Minchanka [31]

Total kicks that were attempted = 40

Goals blocked by Kyra = 55%;

Goals which could not be blocked by Kyra = 100 - 55 = 45%

Goals made during team drill = 18

Let total kicks attempted be 'n';

Therefore;

(18/n) × 100 % = 45 %

18/n = 45/100;

n = 1800/45;

n = 40

Can someone help me.
Helen [10]

The solutions of the equations for x are given as follows:

a. x = 36.

b. x = 15.

<h3>What is the solution for item a?</h3>

The equation for item a is given by:

x/3 - 5 = 7

Isolating x, we have that:

x/3 = 12

x = 3 x 12

x = 36.

<h3>What is the solution for item b?</h3>

The equation for item b is given by:

x/2 - 5 = 2.5

Isolating x, we have that:

x/2 = 7.5

x = 7.5 x 2

x = 15.

Hence the solutions are:

a. x = 36.

b. x = 15.
