Answer:
In this equation x = 2
Step-by-step explanation:
First, it is easiest to convert these words to numbers. That would make it
4 - <em>x </em>· 7 = -10
First subtract 4 from both sides.
4 - <em>x</em> · 7 - 4 = - 10 - 4
Then you simplify.
-<em>x ·</em> 7 = -14
Divide both sides by 7.
Then you simplify that fraction to 2 and thats how you get your answer.
8 x 2 = 16
Square root of 16 = 4
One side of the square is 4 meters.
Answer:
y = 11x - 18
Step-by-step explanation:
Use the equation y = mx + b
m (the slope) = 11
x (the x-coordinate) = 2
y (the y-coordinate) = 4
Plug it in for our original equation:
4 = 11*2 + b
4 = 22 + b
4 - 22 = b
b = -18
Therefore, the answer is y = 11x - 18. The tricks to these problems are usually in the same format, when you are given the slope and a point it passes through, just plug in the slope and the x and y, and solve for b. Hope this helps!
Answer:
$1,5
Step-by-step explanation:
total money spent - cost of magazine = money spent on candy bars
$11 - $5 = $6
money spent on candy bars divided by number of candy bars = price of one candy bar
$6 / 4 = $1,5
The expression would add 6d+7 and 10d+10.
So…
6d+7+10d+10
We add like terms which would be (7 and 10) and (6d and 10d)
7+10 is 17
6d+10d is 16d
So the answer would be
16d +17
