Answer:

4 = x

Step-by-step explanation:

Write the equation out

22 = -6 + 7x

Add 6 to both sides to get rid of the -6

6 + 22= 6 + -6 + 7x

28 = 7x

Divide both sides by 7 to get x alone

28 / 7 = 7x / 7

You should get your answer

4 = x

kramer

Answer:

Sam is 30 years old, and Harry is 10 years old.

Step-by-step explanation:

Let us assume that the age of Sam is x and the age of Harry is y.

Sam is currently is three times Harry's age.

So, $x=3y$ ----------------------1

Sam's age is also 10 more than twice Harry's age.

so, $x=2y+10$ ---------------2

Subtracting 2 from 1, we get

$\Rightarrow x-x=3y-2y-10$

$\Rightarrow 0=y-10$

$\Rightarrow y=10$

putting this in equation 1,

$x=3(10)=30$

Therefore, Sam is 30 years old, and Harry is 10 years old.

alekssr [168]

The correct answers are:
A, B and C.

Explanation: 
A parallelogram is a quadrilateral with both pairs of opposite sides parallel.
A rectangle is a parallelogram with all right angles, so yes, every rectangle is a parallelogram.
A square is a parallelogram with all right angles and all congruent sides; since it is a parallelogram with all right angles, every square is a rectangle.
A rhombus is a parallelogram with all congruent sides.
Since a square is a parallelogram with all congruent sides, then every square is a rhombus.
A trapezoid is a quadrilateral with one pair of parallel sides. Since a rhombus is a parallelogram, with 2 pairs of parallel sides, rhombus are not trapezoids.

23.) 21 hrs at $ 11 per hr = (21 * 11) = 231....and u received 91% of ur wages...
0.91 (231) = 210.21
fraction u got : 210.21 / 231 = 0.91 = 91/100 <== I am not 100% sure on
this. I might be making this harder then it looks....u r going to get 210.31 take home pay.....or 91% which in fraction form is 91/100

26B. 17/10 = 85/ x
cross multiply
17x = 850
x = 850/17
x = 50....50 liters of oil <==

26C. 12:9...added = 21

12/21(4200) = 50400/21 = 2400 <== higher cost receives 2400
9/21(4200) = 37800/21 = 1800
