Answer:
We know that:
She needs 9/10 grams of flour for the cake (this quantity does not make a lot of sense, maybe is written incorrectly, but is the only info we have, so let's solve the problem with this)
She only has 1/3 of the amount she needs.
How much flour does she have?
Well, she needs 9/10 grams, and she has one-third of that.
Then she has (1/3) times (9/10) grams, this is:
F = (1/3)*(9/10) grams
F = (1*9)/(3*10) grams
F = 9/30 grams
That is the amount of flour that she has.
To find the area you times length times width give you the area so 11 X 15 is 165cm squered
The total number of hours was 7 so divide $28.84 by 7 and you'll get $4.12 per hour.

Answer: 4 square inches</h3>
Explanation:
Square the linear scale factor to get 5^2 = 25
This means that,
new area = 25*(old area)
We take this idea in reverse to find the old area
old area = (new area)/25
old area = (100 sq inches)/25
old area = 4 square inches
(1) 12, (2) 5, (3) 13, (4) 30
Step-by-step explanation:
(1) Given expression 2x.
Substitute x = 6 in expression 2x.
⇒ 2 × 6 = 12
(2) Given expression 8 + 3 – x
Substitute x = 6 in expression 8 + 3 – x.
⇒ 8 + 3 – 6 = 11 – 6 = 5
(3) Given expression 6 + 7 – 6 + x
Substitute x = 6 in expression 6 + 7 – 6 + x.
⇒ 6 + 7 – 6 + x = 6 + 7 – 6 + 6 = 13
(4) Given expression 5x
Substitute x = 6 in expression 5x.
⇒ 5× 6 = 30
