Answer:
Step-by-step explanation:
3/4 x 28=21 Madilyn built 21 toys.
1/7 x 28=4 Penelope built 4 toys.
21+4=25 25 toys have been built altogether.
28-25=3
There are 3 toys left to build.
X = dull pencils
y = sharp pencils
x + y = 100
y = x + 16 ~~Plug this back into your original x+y equation.
x+x+16=100 ==> 2x = 84 ==> x = 42. Plug this back into the y = equation
y = 42 + 16 ==> y = 58.
42 Dull, 58 sharp.
total 22 marbles, green and white ones are 5 so 22-5=17 so 17/22 or 17 out of 22
(17.5)(x)=125
Divide each side by 17.5 leaving the equation as x=7.14
Answer:
I believe when you simplify the expression you will get 8a^2 - 20ab. I believe this is the answer. If anything better comes up then please take it because im not sure. Hope I helped!
