Answer:

Step-by-step explanation:

In order to do this you have to understand PEMDAS, which stands for Parentheses,Exponents,Multiplication,Division,Addition,Subtraction. This basically tells us what order we have to do the equation in. So first up, do we have any parentheses? No. Do we have any exponents? No. Okay now, this is what you have to understand. Multiplication and division are on the same level, meaning that if there is any multiplication or division, we do whatever comes first. This also goes for addition and subtraction.

This might sound a bit confusing but let's try! Since division is first, let's do it.

36 divided by 2 is 18.

That means the equation is...

18 x 4+12.

Since multiplication comes after, let's do multiplication now.

18 x 4 =72.

That means the equation is now...

72+12.

Now, our final step is to do addition, so 72+12=84. The answer is 84!

Drew jumped farther than all 4 students above but jumped shorter than 7 feet , 7 inches. How far could drew have jumped? Write s

S_A_V [24]

<h3>The distance covered by Drew in long jump is either 7 ft 5 inches OR 7 ft 6 inches.</h3>

Step-by-step explanation:

Here, the needed table is attached for the reference.

Now, as we can see from the table:

The distance covered by Cindy = 2 yards, 1 foot 3 inches

The distance covered by Tyrette = 7 feet, 2 inches

The distance covered by Nina = 2 yards, 1 foot, 1 inch

The distance covered by Monique = 7 feet, 4 inches

As we know : 1 yard = 3 feet

So, the distance covered by :

Cindy = 2 yards, 1 foot 3 inches = 3 ft x (2) + 1 ft + 3 in = 7 ft 3 in

Tyrette = 7 feet, 2 inches

Nina = 2 yards, 1 foot, 1 inch = = 3 ft x (2) + 1 ft + 1 in = 7 ft 1 in

Monique = 7 feet, 4 inches

So by comparing all distances, we can see that:

The maximum distances jumped by all four is 7 ft 4 inches.

The distance covered by Drew is less than 7 ft 7 in.

So, he must have jumped 7 ft 5 inches OR 7 ft 6 inches.

Hence, the distance covered by Drew in long jump is either 7 ft 5 inches OR 7 ft 6 inches.

Find the value of x

Svet_ta [14]

Answer:

$150^o$

Step-by-step explanation:

<u>Step 1: Distribute the plus</u>

<u /> $(x + 15)^o + (135 - x)^o$

$x + 15 + 135 - x$

<u>Step 2: Combine like terms</u>

<u /> $x + 15 + 135 - x$

$(x - x)^o + (15 + 135)^o$

$0 + 150^o$

$150^o$

Answer: $150^o$

Drag a description to match each equation.

AnnZ [28]

Given:

The descriptions and equations. The equations are

$y=4x$

$y=x+4$

To find:

The correct description for each equation and match them.

Solution:

We know that, "+" is used for more and "×" is used for times.

Additive: y is 4 more than x.

$y=x+4$

Additive: x is 4 more than y.

$x=y+4$

Multiplicative: y is 4 times x.

$y=4x$

Multiplicative: x is 4 times y

$x=4y$

Therefore, the correct description for the equation $y=4x$ is "Multiplicative: y is 4 times x " and the correct description for the equation $y=x+4$ is "Additive: y is 4 more than x. "
