<u>Answer:</u>
The correct answer option is: True.
<u>Step-by-step explanation:</u>
Its true that if there is no linear equation to start with, you can isolate and substitute a variable that is squared in both the equation.
For example, for the given non linear equation, start by dividing both sides by coefficient of the variable.
Once you do that and isolate a variable, continue solving by substituting that variable into the other equation.
Answer:
b
Step-by-step explanation:
The first step is to find out the value of one diaper for each equation
39.98/216 = 0.18
Therefore one diaper is for 0.18 cents
24.99/88 = 0.28
Therefore one diaper is for 0.28 cents
At the end the first deal is better
Answer:
Hence, m∠R=95°.
Step-by-step explanation:
We are given that ΔABC is similar to the ΔRST i.e. ΔABC~ΔRST.
Aslo m∠A=6x+17, m∠B=3x+9, and m∠C=37
We know that sum of all the angles of a triangle is 180°.
⇒ ∠A+∠B+∠C=180
⇒ 6x+17+3x+9+37=180
⇒ 9x+63=180 (As 6x+3x=9x and 17+9+37=63)
⇒ 9x=180-63
⇒9x=117
⇒ x=13. (on dividing both side by 9)
Hence m∠A=6x+17=6×13+17=95°
m∠B=3x+9=3×13+9=48°
m∠C=37°
Also as ΔABC~ΔRST so this implies m∠R=m∠A=95°
Hence, m∠R=95°.
