Step-by-step explanation: 3-2=1+1 hour she took alone = 2hrs
The next number would be 160
For this case, the first thing we should do is use the following equation:
x ^ 2 + x-30
Here, we substitute the value of x = 20
We have then:
(20) ^ 2 + (20) -30 = 390 m ^ 2
Answer:

Answer:
She can make 4 Red Cards and 6 Pink Cards
Step-by-step explanation:
<u>You need to find a common denominator</u>
So if you have 1/2 a yard of red ribbon and you need 1/8 yards of ribbon to make a card - You would do 1/2 times 4 (1x4=4 || 4x2=) = 4/8
And the same for the Red Ribbon
3/4 - (3x2=6 || 4x2=8) = 6/8
