Answer:
-36x+55
Step-by-step explanation:
3(16−4x(3))+7
=(3)(16)+(3)(−12x)+7
=48+−36x+7
next you have to combine like terms
=48+−36x+7
=(−36x)+(48+7)

Fiber one bran cereal boasts that it contains 57% of the Daily Value of fiber you need. If 1 serving contains 15 gram of fiber, how much fiber do you need in one day
Answer:
26.3 grams
Step-by-step explanation:
57% of fiber is 15 grams. To find 1% you would divide 15 by 57 which is 0.2631578947. Now multiply 1% by 100 to get 100% fiber. The amount of fiber needed per day is 26.31578947 (the rounded answer is 26.3)

4. Emily ate dinner at Geisha. Her total was $17.50. A 8% sales tax was
added to her bill. After, Emily added a 20% tip on the total after tax. What
was Emily's final total?
*

Now the tip:
18.90 times .2 = 3.78
18.90 + 3.78 = 22.68
5x+8=2x -13 ?
i need help please
Answer:
x=-7
Step-by-step explanation:
Alrighty. 5x+8=2x-13. Lets do -2x on both sides. We'll get 3x+8=-13. Then lets subtract 8 from both sides. We'll get 3x=-21. Divide by 3 and we'll get x=-7. Hope that makes sense.

change 4x - 5y = 10 into slope intercept form and graph
Answer:
Slope intercept form: y = 4/5x - 2
Step-by-step explanation:
(subtract 4x from both sides) -5y = -4x + 10
(divide everything by -5) y = 4/5x - 2

The volume of this sphere is 972 pi cubic inches. What is its radius?
A sphere.
Recall the formula Sphere Volume = four-thirds pi r cubed
Answer:
Step-by-step explanation:
volume of sphere = 4πr³/3 = 972π in³
r³ = 729 in³
r = 9 in
The value of its radius is,
⇒ r = 6.14 inches
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The volume of this sphere is 972 pi cubic inches.
Now, We know that;
Volume of sphere is,
⇒ V = 4/3πr³
⇒ 972 = 4/3 × 3.14 × r³
⇒ 972 × 3 = 12.56 × r³
⇒ r³ = 232.16
⇒ r = ∛232.16
⇒ r = 6.14 inches
Thus, The value of its radius is,
⇒ r = 6.14 inches

for each sequence find the first 4 terms and the tenth term
a) n squared +3
b) 2n squared
Answer:
Step-by-step explanation:
Given that:
a) n³
The first 4 terms are;
let assume n = 1
1³ = 1
if n = 2
2³ = 8
if n= 3
3³ = 27
if n = 4
4³ = 64
So, the sequence is 1, 8, 27, 64
The tenth term of this sequence is: 10³ = 1000
b)
2n²
if the first term is 1
then 2(1)² = 2
if n = 2
2(2)² = 8
if n = 3
2(3)² = 18
if n = 4
2(4)² = 32
So, the sequence is 1, 8, 18, 32
The tenth term will be 2(10)² = 200

A rectangular dog pen has an area of 64xy square units. The width is 4y. Write an expression for the length.
Answer:
An expression for the length is:
[tex]l=16x[/tex]Step-by-step explanation:
Given
Area of a rectangular dog pen = A = 64xy square units
Width = w = 4y
To determine
The length = l = ?
We know that the area of a rectangular object is
A = l × w
where w is the width and l is the length of the rectangle.
substituting w = 4y and A = 64xy in the equation
[tex]A=l\times w[/tex]
[tex]64xy\:=l\times 4y\:[/tex]
[tex]\:\:l=\frac{64xy\:}{4y\:\:}[/tex]
Divide the numbers: 64/4 = 16
[tex]l=\frac{16xy}{y}[/tex]
Cancel the common factor: y
[tex]l=16x[/tex]
Therefore, an expression for the length is:
[tex]l=16x[/tex]What is the perimeter of this figure

Answer:
6. 60
7. 24.25
8. 28.00111604 or 28
Step-by-step explanation:
30 +90 =120 180-120=60
Sin A = a/c, so a = cSin A. Also Cos A = b/c, so b = cCos A so Sin30=14/c=28
Cos30=b/28 b=24.25
now 14^2+24.25^2=c^2 which gives 28.00111604 or 28
