Step-by-step explanation:
Rate: jumping jacks per minute
Rate of A: 120jjs / 10mins = 12 jumping jacks per minute
Rate of B: 140jjs / 14mins = 10 jumping jacks per minute
Answer:
(m, 3m - 19)
Step-by-step explanation:
Step 1: Define
f(x) = 3x - 19
f(m) = x = m
Step 2: Substitute and Evaluate
f(m) = 3(m) - 19
f(m) = 3m - 19
Step 3: Write as ordered pair
(m, 3m - 19)
Answer:
3x+6=8
Step-by-step explanation:
It says 3 times a number you know that it will be 3 times the variable. Next, it says the "sum of" so you know you will be adding 6 to the multiplication of 3 and the variable to equal 8.
Answer:
From the given information, the value of a is 3 and the measurement of ∠R is 25°
Step-by-step explanation:
For this problem, we have to find the value of a and the measurement of ∠R. We are given some information already in the problem.
<em>ΔJKL ≅ ΔPQR</em>
This means that all of the angles and all of the sides of each triangle are going to be equal to each other.
So, knowing this, let;s find the measurement of ∠R first.
All triangles have a total measurement of 180°. We are already given two angle measurements. We are given that the m∠P is 90° because the small box in the triangle represents a right angle and right angles equal 90°. We are also given that the m∠Q is 65° because ∠Q is equal to ∠K so they have the same measurement. Now, let's set up our equation.
65 + 90 + m∠R = 180
Add 65 to 90.
155 + m∠R = 180
Subtract 155 from 180.
m∠R = 25°
So, the measurement of ∠R is 25°.
Now let's find the value of a.
KL is equal to PQ so we will set up an equation where they are equal to each other.
7a - 10 = 11
Add 10 to 11.
7a = 21
Divide 7 by 21.
a = 3
So, the value of a is 3.
