Let pc be pencils, and pn be pens. Then:
5pc+pn=250
pc+2pn=185
Then
10pc+2pn=500
pc+2pn=185
9pc=315
pc=35
pn=75
Pencils are 35 cents; pens are 75 cents
Answer:
3.2
Step-by-step explanation:
1000 grams in a kilogram
3200/1000=3.2
Answer:
24
Step-by-step explanation:
Using Pythagoras theorem,
a^2 = b^2 + c^2
40^2 = 32^2 + c^2
1600 = 1024 + c^2
1600 - 1024 = c^2
576 = c^2
square root of 576 = c
24 = c
Hey there.
Considering our ratio from fruit to sugar is 2:3, this means we need to make a proportion. I will set this up below;
2:3 = 8:x; x is a variable substitute for our missing sugar value. Let's try to see if 2 divides into 8.
8 / 2 = 4; this means our scale factor of our ratio is 4x larger than the current value, so multiply 2 and 3 by 4 to solve for sugar.
2:3;
2 x 4 = 8; 8:x
3 x 4 = 12; 8:12.
12kg is the missing sugar value in our proportion; therefore, 12kg of sugar is used when 8kg of fruit is used.
I hope this helps!
