Step-by-step explanation:
3(x - 6) = -15 + 3x
Yes no solution show work
Answer:
see explanation
Step-by-step explanation:
Given
3(x - 6) = - 15 + 3x ← distribute parenthesis on left side
3x - 18 = - 15 + 3x ( add 18 to both sides )
3x = 3 + 3x ( subtract 3x from both sides )
0 = 3 ← not possible
This indicates the equation has no solution

Jane's cell phone plan is $58 each month plus $0.20 per minute for each minute over 200 minutes of call time. Jane's cell phone bill last month was $67.00. Write an equation that can be used to determine the number of minutes over 200 that Jane was billed. How many minutes over 200 was Jane billed last month?
Answer: 45 minutes more than 200
Step-by-step explanation:
So for every minute over 200 jane has to pay 0.20 cents per additional minute. The equation we can use is $58+0.20m=$67 where m is the amount of minutes after 200 jane has to pay 20 cents per
58+0.20m=67
0.20m=9
m=45
So Jane was billed for 45 minutes over 200 minutes last month. so in total 245 minutes and she was charged for the extra 45 minutes

Answer:
SI = 2052.61 ft
Step-by-step explanation:
cos 13 = 2000/SI
0.9744 = 2000/SI
multiply both sides by SI:
(SI)(0.9744) = 2000
divide both sides by 0.9744:
SI = 2052.61 ft

The volume = LBH = x²y
.°. If a pyramid and a prism have the same base and height, their volumes are always in the ratio of 1/3xVolume of prism.
The volume of Pyramid = 1/3*x²y
h = 3 *1/3x²y/x²
h = 3*1/3x²y*1/x²
h = 3*1/3y
h= y.

50 elevens-1 elevens
Answer:
Step-by-step explanation:
50 elevens-1 elevens = ( 50 -1 ) elevens = 49 elevens
or 49 x eleven = 49 x 11 = _______ (use your calculator here)
Answer:
( 50 -1 ) elevens = 49 elevens = 49 x 11 = 539
or
50 elevens - 1 elevens = (50 x 11) - (1 x 11)
550 - 11 = 539

Part A
Between which pairs of points are the slopes the same? Select all that apply
B and C; A and C
A and F; A and E
D and E; A and F
C and D; E and F
A and B; B and C
E and F; A and F
Answer: Yes
Step-by-step explanation: It is because it is just a bigger version of it. B is half of C, F is half of E and The A is in both diagrams.
A is the point with coordinates (4, 6)
B is the point with coordinates (d, 21)
The gradient of the line AB is three.
Work out the value of d.
The gradient is the slope.
Slope is the change in y over the change in x.
3 = (21-6) / (d-4)
Simplify:
3 = 15/(d-4)
(D-4) = 15/3
D-4 = 5
Add 4 to both sides :
D = 9

Expanding a garden. The dimensions are 25 feet by 25 feet. I bought 10 cubic yards of soil. How many inches thick will the new dirt cover
Answer:
The thickness of the new dirt cover is 0.144 yards.
Step-by-step explanation:
Dimension of garden = 25 feet by 25 feet.
Volume of soil bought = 10 cubic yards
Volume = length x width x height
But,
1 foot = 0.333333 yard
So that,
25 feet = 25 x 0.333333
= 8.33333 yards
The new dimension of the garden = 8.33333 yards by 8.33333 yards.
Let the thickness of the new dirt cover be represented by h.
Thus,
Volume = 8.33333 x 8.33333 x h
10 = 69.44439 x h
h = [tex]\frac{10}{69.44439}[/tex]
= 0.144
h = 0.144 yards
The thickness of the new dirt cover is 0.144 yards.

1.Write the equation in point-slope form with the given slope of -2 and passes through the point (4,-5)
2. Write the equation in slope-intercept form of the line parallel to y=4x-2 and passes through (4,6)
3. Write the equation in slope-intercept form with the given slope of 3 and passes through (-1,1)
4. Write the equation in slope-intercept form of the line perpendicular to 2x-7y=1 and passes through (0,-4)
The equation in point-slope form: y - y₁ = m(x - x₁)
slope: m = -2
point: (4, -5) ⇒ x₁ = 4, y₁ = -5
Therefore, the equation of the line in point-slope form:
y + 5 = -2(x - 4)2.The equation in slope-intercept form: y = mx + b
Parallel lines has the same slope, so:
y = 4x + 2 ⇒ a = 4
If a line passes through the point (x₁, y₁) then the equation y₁ = mx₁ + b is true.
(4, 6) ⇒ x₁ = 4, y₁ = 6
So: 6 = 4·4 + b ⇒ b = -10
Therefore the equation:
y = 4x - 103.a = 3
(-1, 1) ⇒ x₁ = -1, y₁ = 1
So: 1 = 3·(-1) + b ⇒ b = 4
The equation:
y = 3x + 44.The product of slopes of perpendicular lines is -1.
2x - 7y = 1 ⇒ 7y = -2x + 1 ⇒ y = -²/₇x + ¹/₇
-²/₇×m = -1 ⇒ m = ⁷/₂
(0, -4) ⇒ x₁ = 0, y₁ = -4
-4 = ⁷/₂·0 + b ⇒ b = -4
The equation:
y = ⁷/₂x - 4Mr.Williams bought 30 muffins and pies. Each muffin cost 2.50 dollars and each pie cost 4.50$. The pies cost 9$ more than the muffins. How many of each item did he buy?
