2x -3y =2 x = 6y - 5

never [62]

2(6y - 5) - 3y = 2
12y - 10 - 3y = 2
9y - 10 = 2
9y = 12
y = 4/3, or 1 1/3
2x - 3(4/3) = 2
2x - 12/3 = 2
2x - 4 = 2
2x = 6
x = 3

In a recent survey, 78% of students at Lincoln Middle School said they plan to attend a camp this summer. Write this percent as

prohojiy [21]

Answer:

0.78

Step-by-step explanation:

From the question, we are to represent 78% as a decimal

78% = 78/100

78/100 = 78 * 1/100

78/100 = 78 * 0.01

78/100 = 0.78

hence the percent written as a decimal is 0.78

Hi, there.

For this question, we can apply the Pythagorean theorem $a^2 + b^2 = c^2$ .

I'm sure you've seen this equation before, and they kind of tried to trip you up with this problem. Trust me, it's easier than it looks. Let's break it down.

Lengths a and b both have the value of 48, which means that the value s in $\sqrt{2s^2}$ is 48, because the length of the hypotenuse is the same as the length and height squared multiplied by 2.

Plug in the value for c: $a^2 + b^2 = (\sqrt{2s^2})^2$

Plug in the value for s:

$(\sqrt{2(48^2)})^2$

Do the innermost exponents first:

$(\sqrt{2(2304)})^2$

The square root symbol and the power of 2 cancel each other out, so we are left with:

s = $2(2304)$ , so the hypotenuse is 4608 inches.
