Answer:
x = -2
Step-by-step explanation:
-3(4x + 2) = 18
Divide by -3:
-3(4x + 2) / -3 = 18 / -3
4x + 2 = -6
Subtract 2:
4x + 2 - 2 = -6 - 2
4x = -8
Divide by 4:
4x / 4 = -8 / 4
x = -2
Answer:X=-4
Step-by-step explanation:
Answer:
Ace will work 88 problems correctly out of 100.
Step-by-step explanation:
Given that:
Ace worked out 22 problems out of his 25 activities
Ratio = 22:25
If the number of problems are 100, then x be the number of problems correctly solved by Ace.
Ratio = x : 100
The relationship is proportional.
22:25 :: x:100
Product of mean = Product of extreme
25x = 22*100
25x = 2200
Hence,
Ace will work 88 problems correctly out of 100.
Answer:
D. 270
Step-by-step explanation:
With the information given you can work your way around the table to fill in the blanks
300-120=180 Red-footed one-headed
180+200=380 total red-footed
650-380=270 total black-footed (answer)
270-120=150 black-footed two-headed
150+200=350 two-headed
Answer:
No, there is not a proportional relationship.
Step-by-step explanation:
A proportional relationship is when 2 amounts have the same ratios.
The easiest way to see this is to put them into decimal form.
3/4 is equal to 0.75 (You can find this by dividing 3 and 4 in the calculator)
1 1/4 is equal to 1.25
Kara mixes every 0.75 with 1 egg.
James mixes every 1.25 tablespoons with 2 eggs.
Divide 1.25 by 2 to find out how many tablespoons that James mixes with 1 egg.
1.25 tablespoons /2 = 0.625
2 eggs /2 = 1 egg
Therefore, James mixes 0.625 tablespoons of milk with 1 egg.
They do not mix the same amount of tablespoons of milk for ever ONE egg, meaning that they are not proportional.
