Answer:
$13,400
Step-by-step explanation:
Simple Interest = principal × rate × time
principal= $9000
Rate= 12/100=0•12
Time=5years
Simple interest =PRT
= 9000× 0•12 × 5
= 5400
Total amount to be paid = 9000 + 5400
= $13400
Answer:
<u><em>Answer is below</em></u>
Step-by-step explanation:
<em><u>-2 ×^2 - 4y +6</u></em>
<em><u>Evaluate simply means to form an idea of something</u></em>
<em><u>So Evaluate for x=−3,y=−2</u></em>
<em><u>−2(−3)2−(4)(−2)+6</u></em>
<em><u>−2(−3)2−(4)(−2)+6</u></em>
<em><u>Answer =−4</u></em>
Answer:
65
Step-by-step explanation:
Lets x = # of hours Melania works at <span>office clerk
and y = </span># of hours Melania works as a <span>cashier
x + y = 38 so x = 38 - y
13x + 9.25y = 434
substitute </span> x = 38 - y into 13x + 9.25y = 434
13x + 9.25y = 434
13(38 - y) + 9.25y = 434
494 - 13y + 9.25y = 434
-3.75y = -60
y = 16
x = 38 - y so x = 38 - 16 = 22
answer
Melania works at office clerk = 22 hours
Melania works as a cashier = 16 hours
FOIL and PEMDAS are both ways to solve mathematical equations.
<u>FOIL</u><u />
First
Outside
Inside
Last
<u>PEMDAS
</u>Parenthesis
Exponents
Multiplication &
Division
Addition &
S<u />ubtraction
FOIL is usually used to solve equations in two sets of parenthesis, for example:
(23+x)(5-4x)
PEMDAS is used to solve multiple-operation equations, such as:
5 x 4 + 6 - 2 x 7
Whew, hope this helped :D
