Answer:

Step-by-step explanation:

Let x be the brother's weight.

Then 2x-5 is Andy's weight.

x+(2x-5)=100

3x-5=100

3x=105

(b) Paul uses the function y = 8x + 40 to model the situation. What score does the model predict for 3 h of homework? WILL MARK

Bess [88]

Assuming that $x$ is the amount of hours spent doing homework:

Plug in $3$ for $x$

$y = 8(3)+40$ , $y=64$

That means that since a $y$ value is the test score (because that's what the y-axis is labeled), your predicted test score is a 64.

If the shortest side in a 30° 60° and 90° triangle is a half an inch long find the length of the other two sides

disa [49]

30=1/2 inch
60=1/2x2=1 inch
90=1/2x3=1 1/2

shortest side is 1/2 inch, medium side is 1 inch, longest is 1 1/2

Describe how you would use the Distributive Property to simplify (39 × 5). (2 points)

alexandr402 [8]

Use of distributive property will be
(30 x 5) + (9 x 5)

21. the error for x - 28 = 375 is not 347 is because the student subtracted both sides by 28. 347 - 28 is 319 not 375. One must add 28 to both sides of -28 and 375. The -28 and 28 is zero. 375 + 28 = 403.

22. The next three terms are 0.93, 1.02, and 1.11. The rule in the number pattern is one must add 0.09.

Which fraction has the value that's equal to 3/4

mamaluj [8]

One of the fractions that’s equal to $\frac{3}{4}$ is $\frac{12}{16}$

<u>Solution:</u>

Given that , we have to find fractions which has the same value as that of the fraction $\frac{3}{4}$

Now, we know that, there are several fractions with values equal to $\frac{3}{4}$

To find them, just multiply the numerator and denominator by the same number.

$\begin{array}{l}{3 \times 2=6} \\\\ {4 \times 2=8}\end{array}$

Therefore, $\frac{6}{8}$ is equal to $\frac{3}{4}$

We can do the same with 4, to get $\frac{12}{16}$ , or any other number beyond that.

Hence, one of the fractions that’s equal to $\frac{3}{4}$ is $\frac{12}{16}$
