The fees for school is $47,932 but Juan is get $34,000 so he only has to pay $13,932 on his own
Answer:
a. 0.69x + 0.14
b. 5.67 - 30.48a
c. 1.1x - 3.01y
Step-by-step explanation:
a) 2.56x + 0.14 − 1.87x
<em>To simplify this algebraic expression, you start by collecting like terms;</em>
2.56x − 1.87x + 0.14
<em>Then perform arithmetic operation</em>
0.69x + 0.14
b) 7.32a + 2.1 (2.7 − 18a)
<em>Here; first, the bracket must be opened</em>
<em>To open the bracket; each expression in the bracket is multiplied by 2.1. This leaves us with</em>
7.32a + 2.1 * 2.7 − 2.1 * 18a
7.32a + 5.67 - 37.8a
<em>Then, you collect like terms</em>
7.32a - 37.8a + 5.67
<em>Then perform arithmetic operation</em>
-30.48a + 5.67
<em>Rearrange</em>
5.67 - 30.48a
c) 0.12x + 0.34y + 0.98x − 3.35y
<em>Here, you start by collecting like terms</em>
0.12x + 0.98x + 0.34y − 3.35y
<em>Then perform arithmetic operation</em>
1.1x - 3.01y
Answer:
<h3>Q 1</h3>
<u>Sum of interior angles of a pentagon:</u>
- 4x + 60 = 180(5 - 2)
- 4x + 60 = 540
- 4x = 480
- x = 120
<h3>Q 6</h3>
<u>Midsegment is half of the sum of the bases:</u>
- (2n - 2 + 4n + 6)/2 = n + 12
- (6n + 4)/2 = n + 12
- 3n + 2 = n + 12
- 2n = 10
- n = 5
<u>Midsegment is:</u>
Correct choice is D
<h3>Q 3</h3>
- m∠1 = 90 as diagonals are perpendicular
- m∠2 = 41 as alternate interior angles
<u>∠3 is complementary with ∠2:</u>
None of the choices is correct
Answer:
b=16
Step-by-step explanation:
Formula~ 1/2*b*h
1/2*15*b=120
7.5b=120
b=120/7.5
b=16
(you can substitute the value to check-i've done it below)
1/2*16*15=?
if you work it out, the ans will be 120, therefore the ans is correct!
