(-5) -(7)=?
Helpppppp plsssss
Answer:
-12
Step-by-step explanation:
(-5)-(7) can easily be called -5-7 when all the brackets are taken away
-5-7= -12
Answer:
You can use the additive inverse to solve for x
Step-by-step explanation:
The additive inverse acquits you to change two things: the negative sign and -7
Therefore, after implementing the additive inverse, here's your expression: -5 + -7. Remeber, the rule for adding negative rational numbers: the sum of 2 negative numbers will be negative. Therefore, simply add 7 + 5 to get 12. Remebering out rule of adding negative rational numbers, you should receive -12 as your answer.

Answer:
[tex]\Huge\boxed{74}[/tex]
Step-by-step explanation:
Hello There!
First things first, we need to find the value of x
If you didn't know the measures of supplementary angles add up to equal 180 so we can use this equation to solve for x
180 = 2x + 3x - 5
step 1 combine like terms
2x + 3x = 5x
now we have
180 = 5x - 5 step 2 add 5 to each side
-5 + 5 cancels out
180 + 5 = 185
now we have 185 = 5x
step 3 divide each side by 5
5x/5=x
185/5=37
we're left with x = 37
Now we want to plug in 37 into x for angle A
angle a = 2(37)
2*37=74
so we can conclude that angle A = 74

Let's verify is the corresponding sides have same ratio:
ΔABC, sides: 6, 9, 11ΔXYZ, sides: 21, 31.5, 38.5Ratios:
6/21 = 2/7 (divide by 3)9/31.5 = 2/ 7 (divide by 4.5)11/38.5 = 2/7 (divide by 5.5)The ratios are same, so the triangles are similar
Yes, the sides are all proportionalThe scale factor (ΔABC to ΔXYZ) is 2/7 (or ΔXYZ to ΔABC is 7/2 = 3.5)

Travis wants to build a fence around his mother's rectangular garden. The length of the garden is 315 centimeters, and the width of the garden is 290 centimeters. 799992110.Gif How many meters (m) of fence will Travis need?
Answer: 12.1 meters
Step-by-step explanation:
This is a rectangular fence so it represents a rectangle.
Fencing the garden will require going around it therefore you are looking for the perimeter.
Perimeter of a rectangle = (2 * Length) + ( 2 * Width)
= (2 * 315) + ( 2 * 290)
= 1,210 cm
Convert to meters:
A meter is 100 centimeters
= 1,210 / 100
= 12.1 meters

Let's solve your equation step-by-step.
−4(x−3)=20
Step 1: Simplify both sides of the equation.
−4(x−3)=20
(−4)(x)+(−4)(−3)=20(Distribute)
−4x+12=20
Step 2: Subtract 12 from both sides.
−4x+12−12=20−12
−4x=8
Step 3: Divide both sides by -4.
−4x−4=8−4
x=−2

Answer:
-3x+3=5x+19
5x+3x=3-19
8x=-16
x=-2
Hope this helps <3
Answer:
x = -2
Step-by-step explanation:
we know,
y is common in both
so ,
-3x + 3 = 5x + 19
-3x +3-19=5x
-3x - 16 = 5x
-3x -5x = 16
-8x = 16
x = 16 / -8
x= -16/8
x= -2
also if you put value of x = -2 in both the expression you will get y = 9

Step-by-step explanat
Multiply each term by k k and simplify. T 5 k 3 − 2 3 = 7 k 5k3-23=7k Move all terms containing k k to the left side of the equation. Tap for more steps... − 2 ( 8 k + 1 ) 3 = 0 -2(8k+1)3=0 Multiply both sides of the equation by − 3 2 -32. − 3 2 ⋅ ( − 2 ( 8 k + 1 ) 3 ) = − 3 2 ⋅ 0 -32⋅(-2(8k+1)3)=-32⋅0 Simplify both sides of the equation. 8 k + 1 = 0 8k+1=0 Subtract 1 1 from both sides of the equation. 8 k = − 1 8k=-1 Divide each term by 8 8 and simplify. k = − 1 8 k=-18 The result can be shown in multiple forms.

Based on the scatterplot and computer output, a
reasonable estimate for the stock price for week 95 is:
A popular social media platform has begun offering
stock shares to the public. In the past 2 years, the
price of the stock has generally increased. An
investment specialist gathers data on the stock price
during the past 2 years and creates an exponential
model for estimating the stock price based on the
number of weeks after the first public offering.
Answer:
the 3rd one
Step-by-step explanation:
i just took the test
Based on the model produced by the scatterplot, log of stock prices is calculated from the scatter plot and 10 is raised to the power of the result to obtain the estimated stock price. Hence, a reasonable estimate for the stock price would be ; $185.05
From the scatter plot model :
Week number, x = 95log y = 0.0022(95) + 2.0583
log y = 2.2673
y = estimated stock priceRaise the power of both sides to the power of 10
[tex]y = 10^{2.2673} = 185.054 [/tex]
Therefore, a reasonble estimate for the stock price would be $185.05

Find m∠ J
Use a calculator. Enter only a number
Answer:
26 degrees.
Step-by-step explanation:
We are given
Side KL length which is 46. (let call that side j).Side JL length which is 93( let call that side k).Angle L=90.We are trying to find angle measure of j.
Since we are given a side opposite of our angle we are trying to find and a side adjacent to the angle we are trying to find we are going to use tan ratio.
[tex] \tan(x) = \frac{opp}{adj} [/tex]
[tex] \tan(x) = \frac{46}{93} [/tex]
since we are trying to find the angle measure apply inverse trig function
[tex] \tan {}^{ - 1} ( \frac{opp}{adj} ) [/tex]
Plug 46 for opp and 93 for adj.
[tex] \tan {}^{ - 1} ( \frac{46}{93} ) [/tex]
which is about 26 degrees.
Kiran, Mai, and Tyler went to their school carnival. They all won chips that they could exchange for prizes. Kiran won 2/3 as many chips as Jada, Mai won 4 times as many chips as Kiran. Tyler won half as many chips as Mai. If Jada won 42 chips, how many chips did Tyler, Kiran, and Mai each win?
Answer:
k = 28
m = 112
t = 56
Step-by-step explanation:
From the question, the following equations can be derived
Kiran's chips (k) = 2/3 x J
Mai (M) = 4 x k
Tyler = 1/2 x M
If Jada won 42 chips, Kiran's chips (k) = 2/3 x 42 = 28
Mai = 4 x 28 = 112
Tyler = 1/2 x 112 = 56
