Answer:
[tex]-\frac{7w+4}{2}+w-3[/tex]
Step-by-step explanation:
Is this the correct statement?
[tex]-\frac{1}{2}(7w+4)+\frac{1}{5}(5w-15)[/tex]
If so, here's how. While we're here, you don't actually "solve" an expression, you can only simplify it. Solving it implies solving an equation, and that needs an = sign.
Starting on the left. First, distribute the fraction over the parenthesis:
[tex]-\frac{7w+4}{2}+\frac{1}{5}(5w-15)[/tex]
Then, do the same thing on the right. Distribute the fraction over the parenthesis again:
[tex]-\frac{7w+4}{2}+\frac{5w-15}{5}[/tex]
Here, on the right, 5 and 15 have a common factor of 5. Factor that out:
[tex]-\frac{7w+4}{2}+\frac{5(w-3)}{5}[/tex]
Finally, cancel out the 5s:
[tex]-\frac{7w+4}{2}+\frac{w-3}{1}\\\\-\frac{7w+4}{2}+w-3[/tex]
That's as simplified as it gets.
A circle has a diameter of 15 cm. Find the circumference. . Use 3.14 for π. Round your answer to the nearest tenth. PLEASE HELP!!!
Answer:
47.1 cm
Step-by-step explanation:
The formula for finding circumference is πd. So, plug in the given values and simplify the expression:
d = 15
π = 3.14
15 × 3.14 = 47.1
The circumference of a circle with a diameter of 15 cm and using 3.14 as a substitute for π will be 47.1 cm.
Answer:
[tex]\boxed {\boxed {\sf 47.1 \ cm}}[/tex]
Step-by-step explanation:
The circumference of a circle is the perimeter or the distance around the circle. It is calculated using the following formula:
[tex]c= \pi d[/tex]
The diameter of the circle is 15 centimeters. We are asked to use 3.14 for pi.
d= 15 cm π = 3.14Substitute the values into the formula.
[tex]c= 3.14 * 15 \ cm[/tex]
Multiply.
[tex]c= 47.1 \ cm[/tex]
This number only has numbers in the tenth place, so we don't need to round.
The circumference of the circle is 47.1 centimeters.

If I bought 2.5 pounds of grapes that costs 1.48 per pound, and pay with a $10 gift card how much money remains on the card?
Answer:$3.25
Step-by-step explanation:
Answer:
£6.30

You need to make party favors for a friend's birthday. 48 people were invited,
but you'll only have to make favors for those who say they will attend. Some of
the favors will be yellow and the rest will be xanadu. Make a graph using paper
or technology that shows all of the possible combinations of yellow or xanadu
party favors you might choose to make. Let represent the xanadu favors and
y represent the yellow favors. Your graph should be labeled with x-intercept, y-
intercept, shaded region, linear boundary (solid or dashed). Also include an
additional point with coordinates clearly labeled in the solution region that
shows me how many of each favor you choose to make after all RSVP's are
received.

A TV has a listed price of 767.95 $ before tax.if the sales tax rate is 7.25%, find the total cost of the TV with sales tax included.
round your answer to the nearest cent, as necessary.
Answer:
Total cost of TV = $823.63
Step-by-step explanation:
Total cost of TV = the price of the set + (Cost of TV) × ( Sale Tax %)
Total cost of TV $767.95 + ($767.95 × .0725) remember 7.25% = .0725
Total cost of TV = 767.95 + $55.68 $55.6763 ≈ $55.68
Total cost of TV = $823.63

ou have R45 and a packet of sweets costs R4.25 but you also want to grab a cup of coffee, which costs R12. How many packets of sweets can you buy if you only buy one cup of coffee?
Answer:45+25+12=82
Step-by-step explanation:
Answer:
(45 - 12) / 4.25 = 7.76
Answer is 7 packets of sweets
Step-by-step explanation:
You have R45 and you only need to buy one cup of coffee which costs R12
After you purchased a cup of coffee you will have R33 (45 - 12 = 33)
A packet of sweets costs R4.25.
With R33 you can only buy 7 packets of sweets (33/4.25 = 7.76)

(2n + 1)(6) = 78
(6 × 2n) + (6 × 1) = 78
12n + 6 = 78
12n = 78 - 6
12n = 72
n = 72/12
n = 6 cm
Answer:
6
Step-by-step explanation:
You have to insert each of the numbers in place of n and do the equation to see if it adds up to 78.
2(6) + 1 = 78
the others do not equal 78, therfore n = 6

Solve the formula to solve for L in terms of pie T and g
Answer:
[tex]\frac{T^{2} g}{4\pi ^{2} } =L[/tex]
Step-by-step explanation:
Hey there,
[tex]T=2\pi \sqrt{\frac{L}{g} }\\\frac{T}{2\pi } =\frac{2\pi \sqrt{\frac{L}{g} } }{2\pi } \\\frac{T}{2\pi } =\sqrt{\frac{L}{g} } \\(\frac{T}{2\pi }) ^{2} =\frac{L}{g} \\\frac{T^{2} }{4\pi ^{2} } =\frac{L}{g} \\[/tex]
Use cross multiplication
[tex]T^{2} g=4\pi ^{2} L\\\frac{T^{2} g}{4\pi ^{2} } =\frac{4\pi ^{2} L}{4\pi ^{2} } \\\\\frac{T^{2} g}{4\pi ^{2} } =L[/tex]

Find the quotient of (11 ^ 18)/(11 ^ 3)
Answer:
The first choice, [tex]11^{15}[/tex].
Step-by-step explanation:
The numerator, [tex]11^{18}[/tex], is equivalent to eighteen "[tex]11[/tex]" multiplied together:
[tex]11^{18} = \underbrace{11 \times 11 \times 11 \times 11 \times \cdots \times 11 \times 11}_{\text{$18$ in total}}[/tex].
On the other hand, the denominator, [tex]11^{3}[/tex], is equivalent to three "[tex]11[/tex]" multiplied with one another:
[tex]11^{3} = 11 \times 11 \times 11[/tex].
Dividing [tex]11^{18}[/tex] by [tex]11^{3}[/tex] would eliminate three "[tex]11[/tex]" from the numerator:
[tex]\begin{aligned}& \frac{11^{18}}{11^{3}} \\ =\; & \frac{(11 \times 11 \times 11) \times \overbrace{11 \times \cdots \times 11}^{\text{$(18 - 3)$ in total}}}{(11 \times 11 \times 11)} \\ =\; & \overbrace{11 \times \cdots \times 11}^{\text{$15$ in total}} \\ =\; & 11^{15}\end{aligned}[/tex].
In general, dividing an expression by [tex]y^{b}[/tex] ([tex]y \ne 0[/tex]) is equivalent to multiplying that expression by [tex]y^{-b}[/tex].
For example, in this question, dividing [tex]11^{18}[/tex] by [tex]11^{3}[/tex] would be equivalent to multiplying [tex]11^{18}\![/tex] by [tex]11^{-3}[/tex]. In other words:
[tex]\begin{aligned}& \frac{11^{18}}{11^{3}} \\ =\; & 11^{18} \times 11^{-3} \\ =\; & 11^{18 - 3} \\ =\; & 11^{15}\end{aligned}[/tex].
