Answers

Answer 1

Answer:

if it is 2(x+12=27*6-120

x is 9

if it is really

2x+12=27*6-120

x is 15

Hope that helps

Answer 2

Answer: Let's begin by solving the right side of the equation. 2(x+12)=27*6-120. By the order of operations, PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction), 27*6 must happen first. We can rewrite the equation as 2(x+12)=(27*6)-120. 27*6=162. Let's continue. 2(x+12)=162-120. 162-120=42. So, 2(x+12)=42. Now, we have to isolate x. Let's start by dividing out the 2 on BOTH sides of the equation, to use inverse operations: 2(x+12)/2=42/2. x+12=21. Finally, subtract 12 from both sides. x+12-12=21-12. x=9.

Answer: x=9

Michael made a baby quilt that was 3 feet wide. It's perimeter was 16 feet. What was it's area?

Answers

in this situation you have to remember that this is going to be a rectangle so the with is going to be 3 and the opposite side will be the same size.

if one side is 3 the opposite side is also 3if you subtract their sum from the perimeter 16 it leaves 10 divided by 2 the other sides are 5.Area =bXh.3x5=15 which is the area

Katie said, '' negative numbers are integers.'' what was her error?

Answers

An integer is defined as whole number, or a number that is not a fraction. Any whole number that is negative or positive can be an integer. Technically, not all negative numbers are integers. If the number is not a whole number, it is not considered an integer. For example, -2.5 is not an integer.

Her error was that an integer is not just negative numbers, integers are whole numbers that are not fractions, which mean it could be positive or negative whole numbers.

Answers

1. multiply to -18 add to -17 = Multiplying -18 and 1 will give -18 as the result and then on adding -18 and + 1 the result comes to -17
2. multiply to 36 add to -13 = Multiplying -9 and -4 will give -36 as the result and then on adding -9 and -4 the result comes to -13
3. multiply to -24 add to -5= Multiplying -8 and +3 will give -24 as the result and then on adding -8 and +3 the result comes to -5
4. multiply to -18 add to 7= Multiplying +9 and -2 will give -18 as the result and then on adding +9 and -2 the result comes to 7
5. multiply to -36 add to 9= Multiplying +12 and -3 will give -36 as the result and then on adding +12 and -3 the result comes to 9
6. multiply to 24 add to 10= Multiplying +6 and +4 will give 24 as the result and then on adding +6 and +4 the result comes to 10
7. multiply to 18 add to -9= Multiplying -6 and -3 will give -18 as the result and then on adding -6 and -3 the result comes to -9
8. multiply to -36 add to -16= Multiplying -18 and +2 will give -36 as the result and then on adding -18 and +2 the result comes to -16

What will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 5.5? A rectangle is shown. The length of the rectangle is labeled as 8 cm, and the width is labeled as 6 cm. Perimeter = 50 cm, area = 155.25 cm2 Perimeter = 50 cm, area = 1,452 cm2 Perimeter = 154 cm, area = 155.25 cm2 Perimeter = 154 cm, area = 1,452 cm2

Answers

The perimeter of the rectangle is by definition:
P = 2W + 2L
Where,
W: width
L: long
We have then:
P = 2 (5.5 * 6) +2 (5.5 * 8)
P = 154 cm

The area of the rectangle is by definition:
A = (W) * (L)
Where,
W: width
L: long
We have then:
A = (5.5 * 6) * (5.5 * 8)
A = 1452 cm ^ 2

Answer:
Perimeter = 154 cm, area = 1,452 cm2

Answer:

alf you started at the point (2, 2) and went 8 spaces to the left and 5 spaces down, where would you land? (__,__)

Answers

the answer would be (-6,-3). X goes left (negative) or right (positive). Y goes up (positive) or down (negative). X = 2, & Y = 2. If you go 8 spaces to the left, then (2-8=-6) & if you go 5 spaces down, then (2-5=-3). making your final answer (-6,-3).
