The answer is B. Sorry if I'm wrong.
6 - 2 x 1
= 6 - 2
= 4
We have to use the PEDMAS method in solving all kinds of calculation expression.
P = Parentheses (or brackets)
E = Exponents (or Index)
D = Division
M = Multiplication
A = Addition
S = Subtraction
D. DOQ & BOQ together equals 90 degrees
Answer: <em>$90.00</em>
Step-by-step explanation:
<em>Take this equation </em>
<em>120(n)</em>
<em>n will equal 0.75 since it is 75% of the original price</em>
<em>120(0.75)</em>
<em>$90.00</em>
Answer:
m<RST = 32°
m<TSQ = 58°
Step-by-step explanation:
m<RST here, meaning the angle of the whole diagram is 90 degrees as you can see.
m<RSQ + m<TSQ = m<RST
15x — 43 + 8x + 18 = 90
23x — 25 = 90
+25 +25
---------------------------
23x = 115
/23 /23
----------------------------
x = 5
Now, plug this into the equation for m<RSQ and m<TSQ to find their values.
m<RSQ = 15x — 43
= 15x - 43
= 15(5) - 43
= 75 - 43
= 32
m<TSQ = 8x + 18
= 8x + 18
= 8(5) + 18
= 40 + 18
= 58
Now, check to see if our values are right or not.
15x — 43 + 8x + 18 = 90
15(5) — 43 + 8(5) + 18 = 90
75 - 43 + 40 + 18 = 90
32 + 40 + 18 = 90
90 = 90 <u>CORRECT</u>
