- 4(y-2) = 12
What’s the value of x?
Explain
Answer:
There is no x, so I’ll find y
Step-by-step explanation:
-4(y-2)=12
Multiply -4 with y and -2
-4y+8=12
Then subtract 8 with its self and 12
-4y = 4
now divide both numbers with 4
y= -1

Martina tiled 260 squared feet of her kithchen floor. She picked a tile that is $2.49 per square foot. She paid a 7% sales tax. How much did she spend to buy enough tile for her project
Answer:
$692.72
Step-by-step explanation:
Given data
The total area of tile = 260 squared feet
cost per squared foot of tile= $2.49
Hence the total for 260 squared feet cost will be
=260*2.49
=$647.4
Let us find the amount of 7% Tax
=7/100*647.4
=0.07*647.4
=$45.318
Hence the amount spent in all is
=45.318+647.4
=$692.72

Round 245,675 to the nearest hundred thousand
The solution is, Rounding off 245,675 to the nearest hundred thousand is: 246000.
What is round off?Rounding off means a number is made simpler by keeping its value intact but closer to the next number. It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc.
here, given that,
Round 245,675 to the nearest hundred thousand
we know,
Anything at or above 50 gets rounded up.
49 and below gets rounded down.
so, we get,
here, to the nearest hundred thousand means 675 > 500
so, it will be 5,675 => 6000
we have,
Rounding off 245,675 to the nearest hundred thousand is:
246000
Hence, The solution is, Rounding off 245,675 to the nearest hundred thousand is: 246000.

Determine which pair of points has a negative slope.
(6,9), (5, 7)
(-9, -2), (3,6)
(-8, 1), (8, -8)
(2, -8), (-1, -9)
Answer:
(–8, 1), (8, –8)
Step-by-step explanation:
Answer:
(-8, 1), (8, -8) has a negative slope
Step-by-step explanation:
1). y2 - y1 / x2 - x1
7 - 9 / 5 - 6
= 2
2). y2 - y1 / x2 - x1
6 - (-2) / 3 - (-9)
= 2/3
3). y2 - y1 / x2 - x1
-8 - 1 / 8 - (-8)
-9/16
4). y2 - y1 / x2 - x1
-9 - (-8) / -1 - 2
= 1/3

Step-by-step explanation:
because if you round divide that you get
If sin12 = k determine cos24 in terms of k
Recall the double-angle identity,
sin²(x) = (1 - cos(2x)) / 2
Now if sin(12°) = k, then
k ² = sin²(12°) = (1 - cos(24°)) / 2
→ cos(24°) = 1 - 2k ²

Determine whether the graphs of the given equations are parallel, perpendicular, or neither.
9514 1404 393
Answer:
(c) Perpendicular
Step-by-step explanation:
The slope is the coefficient of x in this slope-intercept form.
The slope of the first line is +1.
The slope of the second line is -1.
The product of the slopes is (1)(-1) = -1. When the product of slopes is -1 for two lines, those lines are perpendicular.
Trinity had $525.38 in a savings account at the beginning of the summer she wants to have at least $200 in the account by the end of the summer she withdraws $25 each week for food, clothes and movie tickets writing in a quality that represents triniti's situation. How many weeks can Trinity withdraw money from her account solve the inequality
Answer:
Trinity can withdraw $25 from her bank account for 13 weeks.
Step-by-step explanation:
If she wants to have at least $200 by the end of summer you need to subtract that much from what she has now. Which would be $325.38. Now you have to divide that number into 25, which should give you the number of week that money would last. That number is 13.0152, you don't need all those extra numbers so just use 13. No to check you work multiply 25 and 13. You get 325.

To begin solving for the total cost of the paint that Ariana needs to buy, we first need to calculate the size of the walls and the ceiling that she is going to paint.
We begin by finding the size for the walls.
We use the formula to find the area of each wall.
We know that the walls are 10-foot squares.
10 x 10 = 100 Square Feet
Each wall will have an area of 100 square feet each, we know that there are 4 walls in the shed.
100 x 4 = 400 Square Feet of walls to paint total.
Now we know that the ceiling will have the same area as the walls.
10 x 10 = 100 Square Feet of ceiling to paint.
Now Ariana goes to the store and finds that a gallon of paint cover 350 square feet. Ariana needs to paint a total of 400 square feet of wall.
400 - 350 = 50 Square Feet remains.
We know that she needs to buy the paint in gallons, so this leaves Ariana with purchasing 2 gallons of Blue paint.
Now Ariana also wants to paint the ceiling white. We know that 1 gallon of White paint is more than enough to cover the ceiling, but she still needs to buy the gallon of paint.
Now we add up all the prices of the 3 gallons of paint.
$26.98 x 2 = $53.96 for Blue Paint
$26.98 x 1 = $26.98 for White Paint
Total cost = $80.94.
Now we know that the sales tax is 5.5% of the total price.
$80.94 x 0.055
Sales Tax = $4.45
Now we simply add the total cost to the sales tax.
$80.94 + 4.45
Total cost with sales tax = $85.39
