Answer:
x = -6
Step-by-step explanation:
1. always group the unknowns in this case, we 'bring' over the -2x to the right side so it becomes
-10 = 2x + 2x +14
2. Move 14 to the left side,
-10 - 14 = 2x + 2x
3. Carry out addition on both sides,
-24 = 4x
4. Simplify: since 24 is divisible by 4, so we divide 4 on both sides
-6 = x
Answer: x=-6.
Step-by-step explanation:
First, we need to choose an x side, and a non-x side. Let's choose the right side as the x side since it's coefficient of x is greater than that of the left side. So, we add 2x on each side to get rid of the x on the left side. Now, we have -10=4x+14. Next, we should subtract 14 from each side to get rid of the non-x terms on the right side. Now, we are left with -24=4x. Finally, we can divide by four on each side to get x=-6.

Answer:
351.68 cm^2
Step-by-step explanation:
We need to find the area of the frame itself. the radius of the inner circle is 12, but the frame has a radius of 4. You add 12 and 4 and you get 16. The formula for area of a circle is A=πr^2. So A= 3.14 x16^2. Then you have A= 3.14x 256 and you get 803.84. But we only want the area of the frame, so you have to get the area of the inner circle and subtract. You get A= 3.14 x 12^2. 3.14x144 is 452.16. 803.84-452.16 is 351.68. Hope this helped. :)
Answer:
351.86cm²
Step-by-step explanation:
12+4=16
(total radius of the whole circle)
use the formula a= πr² to find area
area of the full circle = π*16² (256 π)
256π - area of the smaller circle
256π - π*12²
256 π - 144 π = 112πcm² or 351.86cm² (to 2dp)
Hope this helps!!

What was the value of b?
A. -6
B. -2
C. 2
D. 10
Answer:
C.)
Step-by-step explanation:
4x -20x -5b -x +2=-17x -8
-17x-5b+2=- 17x-8
+17x +17x
-5b +2= -8
-2 -2
-5b = -10
b= 2

A sailboat and catamaran are in a race to see who can sail across the Atlantic ocean the fastest..
.The sailboat covers a distance of 3240 miles in 8 days
.The catamaran covered a distance of 4020 miles in 10 days
If the sailboat is able to maintain a constant rate for 10 days, how many more miles would they have traveled than the catamaran?
Answer:
The sailboat would cover 30 more miles than the catamaran.
Step-by-step explanation:
To find how many miles the sailboat goes in 1 day (unit rate) you divide 3240/8 that gives you 405 miles in one day. Multiply that by 2 to get 810 miles in two days. Add 810+3240=4050. That shows that in 10 days the sailboat would travel 4,050 miles which is 30 miles more than the catamaran.
Find an ordered pair , x y that is a solution to the equation. 5x-y=9
Answer:
(1, -4)
Step-by-step explanation:
In order to find a solution to a linear equation, we can substitute any value for one variable, simplify the equation, and find the value of the other variable to find a solution that is an ordered pair.
Since any value for either variable will do, we can choose something simple, such as 1. I chose to substitute 1 for x into the equation, as seen below.
[tex]5x-y = 9\\5(1)-y = 9[/tex]
Now, all I need to do is solve and isolate y:
[tex]5(1)-y = 9\\5-y = 9\\-y = 4\\y =-4[/tex]
So, with this linear equation, when x equals 1, y equals -4. Thus, a solution to the equation is (1, -4).
