10*0.11515
Step-by-step explanation:
Answer:
x=-10
Step-by-step explanation:
since there's a given 120 degrees, and it's a isosceles triangle, we know that the line adds up to 180 (where the 120 degrees is). so 120+x=180, the interior angle measures 60 degrees. That being said, the 3 angles measure 60 degrees also. now there's a right angle mark on top, so we find the angle of the smaller triangle (near angle 2) by doing 90-60=30 degrees.
angle 2 is said to be x+160, and there's a line, which tells us that they must add to 180.. so x+160+30=180
x+190=180
x=-10.
4(-6x – 3) + 24x = -72x + 132
Step 1 -24x – 12 + 24x = -72x + 132 Distribute Property of Equality
Step 2: –12 = -72x + 132 equivalent
Step 3: -144 = -72x Subtraction Property of equality
Step 4: 2 = x Equivalent / Division property of equality
Answer:
I hope my answer is right but im pretty sure its 26.13 :)
Step-by-step explanation:
We have to multiply 54 * 23, and check where the mistake is.
We start by multiplying 54 by 3, and it gives us 162
Then, we multiply 54 by 20, and it gives us 1080.
Then, we have to add these two results:
The mistake is where 6 is added to 8. It does not give 13, but 14.
The 1 of the 10 goes adding above the 1 in 162.
The result is 1,242.
