Answer:

x = -15/2

Step-by-step explanation:

For this problem, we will simply use equation properties to solve for x.

2x - 5 = -20

2x - 5 + 5 = -20 + 5

2x = -15 ( Add positive 5 to both sides )

2x * (1/2) = -15 * (1/2)

x = -15/2 ( Multiply both sides by 1/2)

Hence, the solution to x is -15 / 2.

Cheers.

Two sides of a triangle measure 9 cm and 23 cm what could be the measurement of the third side of the triangle

Vladimir79 [104]

Pythagorean Theorem: a^2+b^2=c^2
(9)^2 + b^2 = (23)^2
81 + b^2 = 529
b^2 = 529 - 81
b^2 = 448
b^2 =
$\sqrt{448}$
b = 21.2

A school had 400 girls last year and the number of boys was 95 more than that of the girls. This year the number of girls had in

STatiana [176]

Answer: The fraction by what the number of boys had been reduced=1/11

Step-by-step explanation:

Step 1: To calculate the number of boys last year.

According to the question,

The number of boys last year= 400+95

The number of boys last year=495

Step 2: To calculate the number of girls this year.

According to the question,

The number of girls this year= 400 + 400*1/5

The number of girls this year= 480

Step 3: To calculate the number of boys this year.

According to the question,

The number of boys this year= 480 – 30

The number of boys this year=450

Step 4: To calculate the fraction by what the number of boys had been reduced.

The number of boys reduced= the number of boys last year - the number of boys this year

The number of boys reduced= 495 - 450 = 45

The fraction by what the number of boys had been reduced

= The number of boys reduced/the number of boys last year

Therefore,

The fraction by what the number of boys had been reduced= 45/495= 1/11
