Answer:
-7x - 14
Step-by-step explanation:
By simplifying the expression:
-3(2x+5) - (x - 1)
-6x-15 -x + 1
-7x - 14
Answer:
-7x - 14
Step-by-step explanation:
You can use the distributive property to find an equivalent expression.
Distribute -3 to 2x + 5.
(-3 × 2x) + (-3 × 5) = -6x + (-15) = -6x - 15
Distribute -1 to x - 1. (It is -1 because there is always a 1 in front of things like x = 1x and (x + 1) = 1(x + 1). 1 times anything equals the number it is multiplied by. There is a - sign in front of the parenthesis, which makes the invisible 1 a -1.)
(-1 × x) + (-1 × -1) = -x + 1
You can simplify the expression.
(-6x - 15) + (-x + 1) = -7x - 15 + 1 = -7x - 14

Original scale: 1 inch = 8 feet. A parallelogram with a side length of 24 feet. A larger parallelogram with a side length of 72 feet.
Noah planned a parallelogram-shaped sidewalk to lead from the street to the front door of his house. He realized the walkway was too short and he needs to change the length to 72 feet. He wrote a ratio to find the change in the scale factor.
24 ft
72 ft
=
The change in the scale factor is
.
The change of scale means that 1 inch represented
feet, but now 1 inch represents
feet.

Kira has to carry 170 apples from a farm to the market. How many baskets will she need, given that each basket can hold 46 apples?
Answer:
4 baskets
Step-by-step explanation:
Since 170 divided by 46 equals 3 with a remainder of 32, you use the remainder,32, and change it to one more basket so 3+1=4 so Kira needs 4 baskets.
Answer:
Kira will require exactly four baskets.
Step-by-step explanation:
The given information we know is..
- Kira is responsible for transporting 170 apples from a farm to the market.
- Each basket has a capacity of 46 apples.
We must divide 170 apples by 46 apples in order to solve this problem.
170/46 ( When I use the / symbol, it indicates to divide.)
170/46 = 3.69565217391
We'll have to round it up because we can't actually accept 3.69 bags. So the answer is 4 baskets.
Kira will need approximately 4 baskets.
Hope this helps! :D

Since there are parenthesis, you have to do the calculation inside of that
(Also, the negative sign takes over in this part of the question)
-4 - 3 = -7
Now, you have to times the answer you just got to 2^2 which is 4
-7 * 4 = -28
As the final step, you have to add -28 to -1
-28 - 1 = -29
Thus, the answer is -29 Choice D

When doing problems like this, remember the PE part of PEMDAS.
Parentheses
Exponents
You have to do parentheses first. Then exponents.
[tex](-4 + -3) = -7[/tex]
Next, find the value of 2 squared, then multiply the previous sum by 2 squared, also the term for the number times itself.
[tex]2^2[/tex] [tex]= 4[/tex]
[tex]-7 * 4 = -28[/tex]
Now, subtract by -1
[tex]-28 - 1 = -29[/tex]
With that information, the problem is now solved! Your final answer is -29

Someone pls help, I will choose brainliest. Solve for C.
Solve for C. 5²+5²=C²
Step-by-step explanation:
First step: square both 5s.
(1).........5^2 = 5 × 5 = 25
(2)........5^2 = 5 × 5 = 25
2nd step: add them.
C^2 = 25 + 25
3rd: put both sides under square root to find c by cancelling the square root sign [√] with square [ ( )^2 ].
√(C^2) = √(50)

What is the area of the figure
Answer:
5 1/3
Step-by-step explanation:
If you split up this shape into a triangle on top and a rectangle on the bottom you can do
(3 2/3 x 2) / 2
Then you do
5 x 1/3
Then add up the sums and you get the area :)
The upper-left coordinates on a rectangle are (−4,4), and the upper-right coordinates are (4,4). The rectangle has a perimeter of 20 units.
Draw the rectangle on the coordinate plane.
(If you could please graph this as a coordinate plane and not numbers)
Answer:
(4,2) and (-4,2)
Step-by-step explanation:
You can see that we have 2 points, which means we have 2 sides of the rectangle. The length of that side is 8. we know that a rectangle has 2 sets of parallel sides, and that they have 2 sets of equal sides. We now know that there are 2 sides with side lengths equaling 16, which we then subtract from 20. We get 4, which we then divide by 2 because there will be 2 more sides. We then move 2 down from both points and take the point which we get from that, which is (4,2) and (-4,2).

Answer:
m∠CAB = 90°
BD = 9
m∠ABC = 90°
arc AEC = 180°
AD = 14.5
Step-by-step explanation:
Question 1
The angle between the radius and a tangent to the circle is always 90°.
Therefore, as AC is the radius and AB is a tangent segment, m∠CAB=90°
As m∠CAB = 90°, we can use Pythagoras' Theorem to find BC (hypotenuse):
AC² + AB² = BC²
⇒ 8² + 15² = BC²
⇒ BC² = 289
⇒ BC = 17
As CD is the radius, CD = 8
Therefore, BD = BC - CD = 17 - 8 = 9
Question 2
If D is the center, then AC is the diameter. Angles at the circumference in a semicircle are always 90°. Therefore, m∠ABC = 90°
As AC is the diameter, arc AEC is half of the circle.
Therefore, arc AEC = 360° ÷ 2 = 180°
As m∠ABC = 90°, we can use Pythagoras' Theorem to find AC (hypotenuse):
BC² + AB² = AC²
⇒ 20² + 21² = AC²
⇒ AC² = 841
⇒ AC = 29
AD is the radius. A radius is half the diameter.
Therefore, AD = AC ÷ 2 = 29 ÷ 2 = 14.5
I don't understand, pls help meeeeeee
Answer:
Solve for x first.
In order to solve for x, you must set up an equation where the two interior angles (1 and 2) are equal to the exterior angle (3).
Interior angles.
Angle 1 = 3x + 7Angle 2 = 2x + 24Exterior angle:
Angle 3 = 6x + 10Set up the equation:-
(3x + 7) + (2x + 24) = 6x + 10
Group and combine like terms;
(3x + 2x) + (7 + 24) = 6x + 10
5x + 31 = 6x + 10
Get rid of constants;
-10 -10
5x + 21 = 6x
-5x -5x
21 = x, the value of 'x' is 21°.
Now we plug in the value of x into angle 3's equation.
∠3 = 6x + 10
∠3 = 6(21) + 10
∠3 = 126 + 10
∠3 = 136°, ∠3 = 136°.

Answer:
x = 30'
2x = 60'

6x ÷6 = 180 ÷ 6
x = 30'
therefore
2x = 60"
3x = 90'
