7x5=20+8+ Fill in the missing number to make the equation true

1 answer:

3 0

Answer: 7

step-by-step:
okay so first you do 7*5 which is 35 and 20+8 which is 28

then you get 35=28+x (the x is the ‘missing number’)

to find x you subtract 28 from both sides to keep the equation balanced

35-28=28-28+x

so 35-28 is 7 and 28-28 is 0 so then you have 7=x and your answer is 7

you’re doing algebra but instead of using variables your teacher is saying find the ‘missing number’ haha

What ratios are equivalent to 5:6 the options are 14:21 6:10 40:48

g100num [7]

This is simply testing if proportions are valid.

Guess-and-check, so the answer would be 40:48, since 5 x 8 = 40 and 6 x 8 = 48, where 8 is the set "constant" number

Solve x2 + 2x + 9 = 0

Keith_Richards [23]

$x^2+2x+9=0 \\ \\
a=1 \\ b=2 \\ c=9 \\ b^2-4ac=2^2-4 \times 1 \times 9=4-36=-32 \\ \\
x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}=\frac{-2 \pm \sqrt{-32}}{2 \times 1}=\frac{-2 \pm \sqrt{-16 \times 2}}{2}=\frac{-2 \pm 4i\sqrt{2}}{2}=-1 \pm 2i\sqrt{2}$

The answer is D.
