Answers

Answer 1

Answer:

Answer:

$x = 3$

Step-by-step explanation:

$10(3x - 5) = 40 \n first \: you \: need \: to \: distribute \n \n 30x - 50 = 40 \n add \: 50 \: from \: both \: sides \n \n 30x = 90 \n divide \: both \: sides \: by \: 30 \n \n x = 3$

Martin combined different amounts of orange juice, pineapple juice, and strawberry juice to make 1850 milliliters (ml) of fruit punch. The amount of orange juice combined was x ml. The amount of pineapple juice combined was 100 ml more than the amount of orange juice, and the amount of strawberry juice was half the amount of orange juice. This is represented in the equation below:x + (x + 100) + one half x = 1850 What was the difference in the amounts of pineapple juice and strawberry juice Martin combined?

Increase £84 by 3%
thank you!

Answers

If you would like to increase £84 by 3%, you can calculate this using the following steps:

3% * £84 = 3/100 * 84 = £2.52

£84 + £2.52 = £86.52

The correct result is £86.52.

Find the slope of the line

Answers

Line pass to points: (-5;0) and (0;-5)

So:

$\left|\begin{array}{ccc}x&y&1\n-5&0&1\n0&-5&1\end{array}\right|=0\n \n 25+5y+5x=0\n \n 5+y+x=0\n y=-x-5\n \n slope=-1 \ \ \(coeficient \ of \$

For each unit of progress toward the right ... as 'x' increases ...
the line drops one unit.

Its slope is -1.

What is the quotient of -8x^6 over 4x^-3 a) x^9 over 32
b) 4x^9
c) -12 over x^2
d) -2x^9

Answers

(-8x^6) / (4x^3) can be broken down as (-8/4) * (x^6/x^-3)
you should know that -8/4 is -2
the second part is dividing variables at different powers which is kinda like subtracting powers

think of it as x ^ (6-(-3))
you get x^9
-2 * x ^9
= -2x^9

f(s) =10 (s-65)+75

Answers

most of the time it saids that s= a number.

f(s) = 10(s - 65) + 75
f(s) = 10(s) - 10(65) + 75
f(s) = 10s - 650 + 75
f(s) = 10s - 575

Angle Q measures 30 degrees. If angle Q is rotated 15 degrees, what is the measure of angle Q'?

Answers

The measure of angle Q' is 45°.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

∠Q = 30°

∠Q is rotated 15°

This means,

∠Q = 30 + 15 = 45°

Thus,

The measure of angle Q' is 45°.
