Answer:
x=66.667
Step-by-step explanation:
Basically, if y varies directly with a value x, you get an equation of the form y=kx, where k is a constant. To answer the question, first substitute 9 into y, and 24 into x.
9=24k
k=0.375
k is 0.375, so to get x, substitute 0.375 into k and 25 into y
25=0.375x
x=66.667
And we got it!
Answer:
-10
Step-by-step explanation:
Assuming that x-2=-5, we can subtitute it into the equation as follows:
(-5)^2 + 5(-5) - 10, we start off with the exponent according to the order of operations resulting in:
25 + 5(-5) -15, then we do the multiplication next:
25 + (5 * -5 = -25) so:
25 + -25 - 10, the 25s cancel each other out and your left with:
0 - 10 which equals -10
Answer:
The three angles of the triangle are 41°, 56° and 83°.
Step-by-step explanation:
The three angles of a triangle are given by 2x + 1, x and x + 15.
Now, we know the property of triangle, that 180° is the sum of all the angles of a triangle.
Hence, (2x + 1) + x + (x + 15) = 180°
⇒ 4x + 16 = 180
⇒ 4x = 164
⇒ x = 41°
So, 2x + 1 = 83° and x + 15 = 56°
Therefore, the three angles of the triangle are 41°, 56° and 83°.

Step-by-step explanation:
60 / 360 × 2 ×22/7 × 5
110/ 21
5.23m
Step-by-step explanation:
if we had the graph, and equations, we will have to substitute the values of x and y in it, and then the equation shall have the same value of 'm' on the equation:-
y= mx+c, where 'm' is the gradient, and 'c' is a constant.
Done.
