Create an equation with one solution of x = −5.
9x − (x − 3) = 2x − (__ + x)
7.4 #7
Answer:
9x-(x-3) = 2x - (-5 + x)
Step-by-step explanation:
Let's say blank is the variable a.
9x-(x-3) = 2x - (a + x)
Simplify the equation:
9x-(x-3) = 2x - ( a + x)
9x - x + 3 = 2x - a - x
8x + 3 = x - a
7x + 3 = -a
a = -7x - 3
Plug in -5 for x:
a = -7*-5 - 3 = 35 - 3 = 32
a = 32 so the equation with one solution of x = -5 would
9x-(x-3) = 2x - (-5 + x)
25 + (98 - 7) x 4 =?

H. line 6
I. line d
to 12 gives a sum
Answer:
F
Step-by-step explanation:
x-9=15 will equal to 24 so x=24
if Allison is 15 but she is 9 years younger then Pam, Pam is x, so all you have to do is count up from 15, so 15+9 which equals 24 Pam is 24 making F the right choice
The base of the following pyramid is a square. If the surface area of the pyramid is 896 in^2, what is it's volume? Side base length is 14 and distance to middle is 7.
Answer: 457.3
Step-by-step explanation:
[tex]V=\frac{lwh}{3}[/tex]
[tex]V=\frac{14*14*7}{3}[/tex]= 457.3
Answer:
V= 1568 in^3
Step-by-step explanation:
B = 14^2 = 196
896 = 14^2 + 2(14) (l)
896 = 196 + 28 (l)
700 = 281 l
25 = l
7^2 + b^2 = 25^2
49 = 625
24
1/3 (196)(24) = 1568

The price of a cup of coffee has dropped to $2.50 today. Yesterday's price was $2.75. Find the percentage decrease. Round your answer to the nearest tenth of
a percent.
Answer:
9.1%
Step-by-step explanation:
The price of a coffee has dropped to $2.50
Yesterday the price was $2.75
Therefore the percentage decrease can be calculated as follows
= 2.50 - 2.75/2.75 × 100
= -0.25/2.75 ×100
= 0.09090 × 100
= 9.1%
Hence the percentage decrease is 9.1%

Y is 1 1/3 times x.
Which ratio is equivalent to y : x ?
A. 3:3
B. 4:3
C: 7:3
D: 3:7
Answer:
B. 4:3
Step-by-step explanation:
Note: I use the '&' mark to symbolize mixed fractions, since it's easy to mistake the whole number for part of the numerator. Don't do this for assignments, as it's not proper.
1 & 1/3 = 4/3
Thus, the answer is B. 4:3.
Assume that random guesses are made for eight multiple choice questions on an SAT test, so that there are n= 8 trials, each with probability of success (correct) given by p=0.3. Find the indicated probability for the number of correct answers. Find the probability that the number x of correct answers is fewer than 4
Answer:
0.80589
Step-by-step explanation:
So all of the numbers of correct answers less than 4 are 0,1,2,3
We need to calculate the probability for each separately and then add them together.
To find the probability we have to first find the combination. We know that there’s n=8 trials and that p=0.3. So 1-0.3 gives us 0.7.
The combination formula is: ! / (!(−)!)
So the n would always =8, and the r would be 0,1,2,3. So you would have to calculate it for 0,1,2,3 Separately. This can be done by hand or you can use a simple combinations calculator online.
For 0;
The combination is 1,
1 x 0.3^0 x 0.7^8-0 =
0.057648
For 1;
The combination is 8,
8 x 0.3^1 x 0.7^8-1 =
0.19765
For 2;
The combination is 28
28 x 0.3^2 x 0.7^8-2 =
0.296475
For 3;
The combination is 56
56 x 0.3^3 x 0.7^8-3 =
0.254122
All that’s left is to add these four numbers;
0.057647 + 0.19765 + 0.296475 + 0.254122 = 0.80589
Using the principle of binomial probability, the probability of correct answers fewer than 4 is : 0.8059
Recall the binomial probability formula :
P(x = x) = nCx * p^x * q^(n-x)
Where :
n = number of trials x < 4 p = probability of success = 0.3q = 1 - p = 1 - 0.3 = 0.7P(x < 4) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3)
Using a binomial probability calculator :
P(x = 0) = 0.0576P(x = 1) = 0.19765P(x = 2) = 0.29648P(x = 3) = 0.25412Therefore,
P(x < 4) = (0.0576+0.19765+0.2965+0.25412) = 0.8059Learn more : https://brainly.com/question/12474772

Answer: 1. 3/8-1/4=1/8
2. 3/8+1/4=5/8
3. x=5/8
Step-by-step explanation: 1. you have to subtract 3/8 by 1/4 because you have to use the largest number to subtract for the smallest number so 3/8-1/4=1/8
2. Add by adding 3/8 by 1/4 because you have to find the value of x so 3/8+1/4=5/8
3. look at number 2. and the answer is x= 5/8

A box of staples contains 6 x 103 staples and weighs 12 oz. How much does one staple
weigh? Write your answer in scientific notation. Round your answer to the nearest tenth, if
necessary.
Answer:
2 * 10^-3 oz
Step-by-step explanation:
Given that:
Number of staples per box = 6 * 10^3
Weight of staple box = 12 oz
Weight per staple = (weight of staple box / number of staples per box)
Weight per staple = 12 / 6 * 10^3
Weight per staple = 12 / 6 * 1000
= 12 / 6000
= 0.002 oz
= 2 * 10^-3 oz

Reset
Answer:
A. 0, - 9
Step-by-step explanation:
Given
x² + 9x = 0
x (x + 9 ) = 0
Either
x = 0
or,
x + 9 = 0
x = - 9
Hope it will help :)
The values of x that satisfy the equation x² + 9x = 0 are x = 0 and x = -9.
Option A is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
x² + 9x = 0
To solve for x, we can factor the expression:
x(x + 9) = 0
According to the zero product property, this equation is satisfied if either x = 0 or x + 9 = 0.
We have two solutions:
x = 0 or x = -9
Therefore,
The values of x that satisfy the equation x² + 9x = 0 are x = 0 and x = -9.

Able is carving a rectangular pyramid clock out of green quartz. The length of the rectangle base is 14 cm and the height of the clock is 9cm. If the clock needs to have a volume of 168cm3 what is the width of the base
Answer:
14cm
Step-by-step explanation:
Volume of the pyramid = Base area × height/3
V = BH/3
Base area = 14×width
Height= 9cm
Volume = 168cm³
Substitute into the formula
168 = 4w×9/3
36w = 168×3
36w = 504
w = 14cm
Hence the width of the pyramid is 14cm
