Answer:
x=112
Step-by-step explanation:
First, let's get all of the fractions to a common denominator.
Based on the numbers given (8,56, and 7), let's make all of the denominators be 56
for , multiply the numerator and denominator by 7.
×=
we can leave as it is
and for , we cam multiply the numerator and denominator by 8
×=
Here's the equation now:
-+=-92
now simlify the fractions
numerators:
-49x-5x+8x=-46x
here's the fraction now:
=-92
We can simplify the fraction by 2 so it's
=-92
now multiply both sides by , which is the reciprocal of (to isolate the variable)
×=-92×
x=112
Hope this helps!
Answer:
12 shirts
Step-by-step explanation:
find the price of 2 shirts:
(1/2 x 34.98)+34.98=52.47
for every 2 shirts she buys, she pays $52.47
314.82/52.47=6
she bought 6 pairs= 12 shirts
Answer:
y=4x+7.75; continuous
Step-by-step explanation:
Let's get the equation first. So she needs one piece that's 7.75 inches long: that's a given.
y = 7.75
Now for each piece of yarn - and she needs 4 pieces - they will be x length. If she wanted them to be 1 inches in length, she would use 4 inches of yarn. So multiply those:
<u>y = 7.75 + 4x</u>
So is this graph discrete or continuous? Remember that continuous means no holes, not stopping, a nice line. Discrete means it has holes or gaps. (In science, we would call discrete "quantized.") In this case, x will be <u>continuous, </u>because Julie can cut any length of yarn for the 4 pieces. She need not choose an integer value. Each piece could logically be 2.5 inches, or 3.1415 inches.
Answer:
n = 121
Step-by-step explanation:
Given,
Amount invested = $250,000
Quarterly payment (P) = $5500
Interest Rate (Quarterly) (r) = 8% /4 = 2%
Account balance = $ 0
Present value of Annuity formula ,
Present value =
1.02⁻ⁿ = 0.091
-n ln(1.02) = ln (0.091)
n = 121
Hence it will take 121 Quarters to account balance $0.
