That is 2(1/7 + 1/2)
= 2( 2/14 + 7/14)
= 2 * 9/14
= 18/14 = 9/7 units ( or 1 2/7 units)
What you need to do is plug in the values of the variables, 4(4)-7, because a=4.
Next, you solve; 4(4)-7= 16-7 = 9.
In conclusion, the expression equals 9.
Answer:
7 quarters and 3 dimes
Step-by-step explanation:
x: quarter y: dime
25x + 10y = 205
x+y=10
y = 10-x
25x + 10*(10-x) = 205
25x+100 -10x = 205
15x = 105
x = 7
7 = 10-7 = 3
Ok so this is a simple question and this is the step by step on how to solve it.
1. take 65 · 15 to get 975 meters in 15 seconds
2. take 975 · 3.3 to get 3217.5 feet pet 15 seconds.
thus making the answer 3217.5 ft
Hope this helped :)
3/4 all over 2/3 equal to x/1 cup
So 3/4 / 2/3 =x/1 now you can cross multiple so 3/4*1=3/4 then 2/3*x=2x/3 then you can solve for x.
3/4=2x/3 multiple 3 to both sides so the 3 cancels with the denominator of 2x
9/4=2x then divide by 2 to both sides to get x alone
9/8=x
1.125=x
So for every 1 cup of white sugar you need 1.125 cups of brown sugar.
