absolute value for a negative number will always be the opposite and absolute value for a positive number will still be positive. for example the absolute value of -5 would be 5. the absolute value of 45 would just be 45. does that help?
ANSWERS:
A: 40 because the distance from 0 to 40 is 40
B: 40 because the distance from 0 to -40 is 40

John will have company when:

He rides with his friends(0.11 probability).

His parents take him(0.53 probability).

The recipe calls for 2 2/4 but jams only have 1/4 how many cups do jams need to measure out 2 2/4 cups of raisins

Answers

Answer:

brainliest

Step-by-step explanation:

she needs altogether 2 2/4.

that is 2 wholes and 2/4 fraction.

if we consider using 1/4 cup, 1 whole is made of four quarter cups.

Therefore 2 wholes require eight quarter cups. then theres a remaining fraction of 2/4 which is equivalent to two quarter cups.

1/4 + 1/4 = 2/4. therefore altogether  8 + 2 = 10 of the 1/4 cups are required for the recipe.

10 of 1/4 cups are needed

Answers

Answer:

x = 1 and y = -2

Step-by-step explanation:

Given that,

2x-3y = 8 ..(1)

4x+3y = -2 ..(2)

Add equation (1) and (2),

2x-3y+4x+3y = 8+(-2)

6x = 6

x = 1

Put the value of x in equation (1).

2-3y = 8

2-8 = 3y

-6 = 3y

y = -2

Hence, the value of x is 1 and that of y is -2.

A. 26 and 10
B. 18 and 8
C. 21 and 15
D. 14 and 10

Answers

Answer:

Step-by-step explanation:

a/b=7/5

a=7b/5

a+b=36, using 7b/5 for a we have

7b/5+b=36

7b/5+5b/5=36

12b/5=36

12b=180

b=15, and since a=7b/5

a=7(15)/5

a=21

So the numbers are 21 and 15

Holly missed 7 of 183 school days this year. Approximately what percent of school days was Holly in attendance? OA. 26% B. 96% OC. 74% Reset Submit 7 of 10 Answered Session Tuner: 30-32 Session Score:​

Answers

Answer:

B: 96%

Step-by-step explanation:

Since 7 out of 100 is 7% (7÷100=0.07)

then 7÷183=0.038 or 0.04. So 4% of the days she was absent. 100%-4% is 96% so holly was in attendance for 96% of the days.
