Answer:

3x = 95

95 ÷ 3 = 31.6666......

I used bus stop method to work this out

Therefore the estimate would be:

x = 32 or 31.7 depending on how accurate it needs to be.

You could alternatively change 95 to 96 and calculate it easily like that

7 + x > 16 Pleas I need Help !!!

Step 1: Simplify both sides of the inequality.

x+7>16

Step 2: Subtract 7 from both sides.

x+7−7>16−7

The answer is x>9

Hope this helped :)

1. Dalia makes a cranberry apple punch that contains 20%, percent real juice by mixing x gallons of a cranberry drink with y gal

Vladimir79 [104]

Answer:

The required equations which represents the relationship between x and y is $0.2(x+y)=0.4x+0.1y$ .

Step-by-step explanation:

Consider the provided information.

Dalia makes a cranberry apple punch that contains 20%, percent real juice by mixing x gallons of a cranberry drink with y gallons of an apple drink.

This can be written as: $\frac{20}{100}(x+y)$

The cranberry drink contains 40 percent real juice and the apple drink contains 10 percent real juice.

This can be written as: $\frac{40}{100}x+\frac{10}{100}y$

Now both the equation are equal.

$\frac{20}{100}(x+y)=\frac{40}{100}x+\frac{10}{100}y$

$0.2(x+y)=0.4x+0.1y$

Hence, the required equations which represents the relationship between x and y is $0.2(x+y)=0.4x+0.1y$ .

Evaluate the expression 5(7 − 4)2 ÷ 3 + 11. (5 point)

ch4aika [34]

Remember PEMDAS.
Parentheses first, which is 3. So then that is 5 times 3 times 2 divided by 3 +11
Simplify, 15 times 2 divide 3 +11
30divide 3 +11
10+11
answer is 21

Answer:

Step-by-step explanation:

The red graph is the black one times 2.

So y = 2 f(x). which is the same as y/2 = f(x) (divide by 2).

Whoever give me the answer to this i will mark them as the Brainest if x = 5,y = 2 and z = 3 then xz ( 4y- 2z) is A. 3445 B. 210

max2010maxim [7]

x= 5 x z= 3 = 15 (4y - 2z) = 60 - -30 = 30 so its C
