Answer:

You can use a ratio to solve this problem. Use x as a variable for the cups of food in 28 days.

1 (day): 3 (cups)

28 (days): x (cups)

Cross multiply.

x=28(3)

x=84

So, Li’s dog eats 84 cups of food in 28 days.

Katy invests a total of $26,500 in two accounts paying 4% and 9% annual interest, respectively. How much was invested in each ac
White raven [17]
A = amount invested at 4%.

b = amount invested at 9%.

we know the total amount invested was $26500, thus a + b = 26500.

whatever% of anything is just (whatever/100) * anything.

how much is 4% of a?  well, is just (4/100) * a, or 0.04a.

how much is 9% of b?  well, is just (9/100) * b, or 0.09b.

we know the interest yielded for both amounts adds up to $1510, thus 0.04a + 0.09b = 1510.

\bf \begin{cases}
a+b=26500\implies \boxed{b}=26500-a\\
0.04a+0.09b=1510\\
----------------\\
0.04a+0.09\left( \boxed{26500-a} \right)=1510
\end{cases}
\\\\\\
0.04-0.09a+2385=1510\implies -0.05a=-875
\\\\\\
a=\cfrac{-875}{-0.05}\implies a=17500

how much was invested at 9%?  well, b = 26500 - a.

jonathan has a collection of 400 marbles. Blue marbles make up17%, percent of his collection. How many blue marbles does Jonatha
dsp73
17% of 400 is 68.
Another way u can do it is 17% of 100 four times since its easier to do. 
17% of 100 is 17.
we have to do this 4 times since 100 goes into 400 four times.
So 17*4 =68

Answer CORRECTLY !!!!! Will mark brainliest !!!!
mash [69]

Answer:

g(q) = \frac{5q}{8}

Step-by-step explanation:

Given

- 7q + 12r = 3q - 4r

Rearrange making r the subject

Add 7q to both sides

12r = 10q - 4r ( add 4r to both sides )

16r = 10q ( divide both sides by 16 )

r = \frac{10q}{16} = \frac{5q}{8} , thus

g(q) = \frac{5q}{8}
