Answer 1

Answer: 1 is b

2 is c

3 is c

4 is d

5 is b

Answer 2

Answer:

12=3x-6 is 6

16=4x+8 is 2

4z+8=40 is 8

5x-7=38 is 9

-3x-9=24 is -11

Step-by-step explanation:

for 12=3x-6 you would get x by itself so first you add the 6 to the 12

you get 18 then you try to get the x by itself so you divide 3x by 3 and divide 18 by 3 as well. So you end up with 6=x. Repeat with every problem

Patty can make 10 purses in 8 hours. At this rate, how many purses can she make in 28 hours? ​

Answers

Answer:

35 purses

Step-by-step explanation:

Set up a proportion, where x is the number of purses she can make in 28 hours:

[tex]\frac{10}{8}[/tex] = [tex]\frac{x}{28}[/tex]

Cross multiply and solve for x:

8x = 280

x = 35

If a piece of ribbon is 4 and 3 over 4. feet long, how long is it in inches?

48 inches

Answers

Answer:

57

Step-by-step explanation:

just trust me i know it i did the math

4 ¾ feet = 4 × 4 + 6 / 4

4 ¾ feet = 19/4 feet

1 foot = 12 inches

Then , 19/4 feet = 19/4 × 12 inches

= 19/4 × 12

= 19 × 12 / 4

= 228/4 inches

= Both the numerator and denominator are divisible by 4 .

Hence ,

= 228 ÷ 4 / 4 ÷ 4

= 57/1

= 57 inches

Therefore , a piece of ribbon which is 4 ¾ feet long in inches :

Hey there!

Let's write this as a ratio/proportion.

The sum of this basic ratio is 4.25.

To figure out how much of each we have for 34, we divide this 34 by 4.25, our sum of the two ingredients. This will give us a factor we can multiply our two ingredient measurements by.

34/4.25=8

Now, we multiply our two ingredients by eight.

2.75(8)=22

1.5(8)=12

Note that these two add up to make 34 tablespoons.

Therefore, we have...

22 tablespoons of olive oil and 12 tablespoons of balsamic vinegar were used in the 34 tablespoons of bread dip.

I hope this helps! Have a great day! :)
