⓵ You need to solve the left side first in order to isolate the × and find it’s value :
-7× + 6 = 27
-6 -6
↓
-7× = 21
÷-7 ÷-7
↓
× = -3
If you find it too difficult to divide a number by a negative, just divide 21 by 7 and always remember that when dividing, when the signs are different the answer is negative. So knowing that you could just divide 21 by 7, which is 3, and add a negative sign in front!
I hope this helped, if there’s anything let me know! ☻
Answer:
31.04%
Step-by-step explanation:
So he increased 17%, then increased 12%.
When he increased by 17%, his height was 117%, relative to his former height. 12% of 117% is 14.04%
So he increase 17%, then increased 14.04% ( of his original height) so his total growth was 31.04%
Answer:
around 1.67 inches
Step-by-step explanation:
We have to divide 1.25 inches by 0.75 inches to get the scale factor.
Hey there! :)
Answer:
y = 1/4x - 3.
Step-by-step explanation:
Use the slope-formula to find the slope of the line:
Plug in two points from the line. Use the points (-4, -4) and (0, 3):
Simplify:
m = 1/4.
Slope-intercept form is y = mx + b.
Find the 'b' value by finding the y-value at which the graph intersects the y-axis. This is at y = -3. Therefore, the equation is:
y = 1/4x - 3.
Answer:
C because ≤ means less than or equal to.
