Answer:

A. 1.2x = 78

B. x = 65

Step-by-step explanation:

Just informally, first:

x is the number that we don't know. 120% of that number is a number BIGGER than that number. 120% of x is 78. So 78 is BIGGER than the number that we don't know.

120% of x = 78

Change 120% to a decimal by moving the decimal two places to the left. Multiply.

1.2x = 78

To solve, divide both sides by 1.2

x = 78/1.2

x = 65

Which value of y mAkes the equation below true. 3y+8-7y=11

victus00 [196]

We have
$3y+8-7y=11$
First, we can combine like terms 3y and -7y to get -4y.
Then, we have $-4y+8=11$ We could then subtract 8 on both sides to get $-4y=3$
Finally, we isolate y completely by dividing both sides by -4, to get
$y=- \frac{3}{4}$

Answer:

p = 0.52392

Step-by-step explanation:

Here we have

p = 23% = 0.23

$\hat p$ = 208/800 = 0.26

n = 800

q = 1-p = 0.77

α = 5% = 0.05

Here we have

Z test given by

$z=\frac{\hat{p}-p}{\sqrt{\frac{pq}{n}}}$

From which we have

From the Cpdf we have Probability = 0.0219, z = 2.016

Therefore from the z score = 0.0683, p = 0.52392 from z table.

I will solve your system by substitution.2x+3y=2;x+6y=4xStep: Solve2x+3y=2for x:2x+3y+−3y=2+−3y(Add -3y to both sides)2x=−3y+22x2=−3y+22(Divide both sides by 2)x=−32y+1Step: Substitute−32y+1forxinx+6y=4x:x+6y=4x−32y+1+6y=4(−32y+1)92y+1=−6y+4(Simplify both sides of the equation)92y+1+6y=−6y+4+6y(Add 6y to both sides)212y+1=4212y+1+−1=4+−1(Add -1 to both sides)212y=3212y212=3212(Divide both sides by 21/2)y=27Step: Substitute27foryinx=−32y+1:x=−32y+1x=−32(27)+1x=47(Simplify both sides of the equation)Answer:x=4/7 and y=2/7
