2. Translate the following equation into a verbal sentence. x + 5 = 2(7 + x)

Stells [14]

Answer:

Step-by-step explanation:

Some points to note

"is" means equal
"times" means multiplication
"quotient" means division
"sum" is addition

Now, let's look at the left side of the equation.

It is "x + 5"

This means the sum of the number x and 5, or the number x plus 5

It eliminates F and J

Now, let's look at right side of equation.

It is "2(7+x)"

"7+x" is in brackets, so this is the sum of 7 and x. Then it is multiplied by 2. Thus, we can say:

"2 times the sum of 7 and x"

From the choices G and H left, we select G to be correct.

The answer is a, this is because 5(2+4) is the same as multiplying 5 by 6 to get 30. The reason we do this is because the length of the entire side is the sum of the bottom numbers

Answer:

Step-by-step explanation:

hello

$2x+2=6 2x+2-2=6-2 \ \ \ substract \ \ 2\\ 2x = 4 \dfrac{2x}{2}=x=\dfrac{4}{2}=2 \ \ \ divide \ \ by \ \ 2\\$

so the solution is 2

$5x+4=8 5x+4-4=8-4 \ \ \ substract \ \ 4\\ 5x = 4 \dfrac{5x}{5}=x =\dfrac{4}{5} \ \ \ divide \ \ by \ \ 5$

so the solution is 4/5

hope this helps

A dairy farmer wants to mix a 85% protein supplement and a standard 55% protein ration to make 1200 pounds of a high-grade 80% p

mr_godi [17]

The diary farmer should use 1000 pounds of 85 % protien and 55 % of 200 pounds to make 1200 pounds of a high-grade 80% protein ration

Solution:

Let the amount of 85 % protien supplement be "x"

Then amount of 55 % protien be (1200 - x)

According to given question,

85 % of "x" protien supplement + 55 % of 1200 - x protien used to get 80 % of 1200 pounds

85 % of x + 55 % of (1200 - x) = 80 % of 1200

$\frac{85}{100} \times x + \frac{55}{100} \times (1200 - x) = \frac{80}{100} \times 1200\\\\0.85x + 0.55(1200 - x) = 960\\\\0.85x + 660 - 0.55x = 960\\\\0.3x = 960 - 660\\\\0.3x = 300\\\\x = 1000$

Pounds of 85 % protien used = 1000 pounds

Then pounds of 55 % protien used = 1200 - 1000 = 200 pounds

Thus he should use 1000 pounds of 85 % protien and 200 pounds of 55 % protien to get 1200 pounds of a high-grade 80% protein ration

HELP!

bearhunter [10]

Here is how you would work it out step by step.

You have to factor the equation you're given. (To check you factorization you can "FOIL" it and make sure it matches the original equation)

Then set the two answers you get from FOILing to zero and you should get your answers.
