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.
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).

Step-by-step explanation:
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.
The inequality x ≥ 25 can be used to represent the distance an athlete runs each week, where x is the distance in miles.
Which of these statements best describe the distance run by the athlete each week?
1. The distance is more than 25 miles.
2.The distance is no more than 25 miles.
3.The distance is at least 25 miles.
4.The distance is less than 25 miles.

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!!

A. -6
B. -2
C. 2
D. 10
Answer:
C.)
