A school snack bar sells a mix of granola and raisins. The mix includes 2 pounds of granola for every 3 pounds of raisins. How m

kifflom [539]

The easiest way to solve a problem like this is to cross multiply and solve

The problem gives us a ratio
2 pounds of granola = 3 pounds of raisins
which makes a ratio of $\frac{2}{3}$
The other ratio is
? pounds of granola = 24 pounds of raisins
which makes a ratio of $\frac{x}{24}$

To solve, set them equal to each other ...
$\frac{2}{3} = \frac{x}{24}$

Now we must cross multiply...
To cross multiply, we multiply 2 and 24
and we multiply 3 and x
Now we have an equation to solve!
3x = 48
To solve and get your final answer, divide...
x = $\frac{48}{3}$

x = 16
You'll need 16 pounds of granola

1.what is the value of x? ( 1st pic)

balandron [24]

For the first picture using Pythagorean Theorem, we know that a^2 + b ^2 = c^2 but since we only know c ( 99.2) and b ( 62 ) we need to use the theorem to find a the equation we use for that is :
A = square root of ( c^2 - B^2 )
A = 77.44

Breann solved the system of equations below. What mistake did she make in her work? 2x + y = 5 x − 2y = 10 y = 5 − 2x x − 2(5 −

goldfiish [28.3K]

Answer:

No mistake

Step-by-step explanation:

2x + y = 5

x - 2y = 10

y = 5 - 2x

x - 2(5 - 2x) = 10

x - 10 + 4x = 10

5x - 10 = 10

5x = 20

x = 4

2(4) + y = 5

y = -3

She made no mistake

You can check by plugging in x = 4 and y = -3 into the original equations . They fit exactly.
