Answer: 4(x+3)= 8x-12
Step-by-step explanation:
2x-5y=9
3x+4y=2
Simultaneous equation find x and y
Answer:
x = 2
y = -1
Step-by-step explanation:
2x - 5y = 9
3x + 4y = 2
find x in terms of y using the first equation
2x - 5y = 9
2x = 9 + 5y
x = 4.5 + 2.5y
substitute x for 4.5 + 2.5y in the second equation
3x + 4y = 2
3(4.5 + 2.5y) + 4y = 2
13.5 + 7.5y + 4y = 2
13.5 + 11.5y = 2
11.5y = 2 - 13.5
11.5y = -11.5
y = -1
now substitute y for -1 in the first equation
2x - 5y = 9
2x + 5 = 9
2x = 9 - 5
2x = 4
x = 2

с
D
Write a list of steps that are needed to find the measure of ZB.
Step-by-step explanation:
the exterior angle is equal to the sum of the interior angles on the opposite side.
As in angle BCD = angle BAC + angle ABC
113 = 72+angle ABC
angle ABC = 41
Answer:
180-113 to find the linear angle.
add that result with 72.
once found the sum, use 180 to subtract the sum to get angle B.
A shopkeeper purchased 100 blankets at Rs. 2000 each. He found that 10 blankets were
defective and he sold these at Rs. 1200 each. At what rate should he sell the remaining
blankets so as to gain 14% on the whole ?
Answer:
2,400.
Step-by-step explanation:
Since the shopkeeper bought 100 blankets at $ 2000 each, he spent a total of $ 200,000. He wants to make a total profit of 14% through his sale, that is, he wants to make sales for $ 228,000 (200,000 x 1.14).
Since he sold 10 defective blankets at $ 1200 each, he recovered a total of $ 12,000. Therefore, he has $ 216,000 (228,000 - 12,000) left to achieve his goal, through the sale of 90 blankets. Therefore, you must sell each blanket for $ 2,400 (216,000 / 90) to make the desired profit.

What is the image of (5, -7) after a dilation by a scale factor of 3 centered at the
origin?
Answer:
The image of the point after the dilation is (15,-21).
Step-by-step explanation:
To find the image of a point after a dilation by a factor, we multiply each coordinate in the point by the factor.
In this question, we have that:
Point (5,-7)
Dilation by a scale factor of 3, centered at the origin. So, multiply by 3
5*3 = 15
-7*3 = -21
The image of the point after the dilation is (15,-21).
Answer:-21,15

The fastest time for completing an obstacle course is 218 seconds. Artest completed the first half of the course in 95 seconds. It took him 124 seconds to finish the second half. a. What is Artest's total time? b. How does his time compare to the fastest time?
Answer:
219 Seconds ; He was 1 second faster
Step-by-step explanation:
Two halfs equal one whole, meaning both of the times added will equal the full time he took:
95+124=219
219 Seconds
He was 1 second faster because:
219-218=1

The SAT is standardized to be normally distributed with a mean µ = 500 and a standard deviation σ = 100. What percentage of SAT scores falls:_____.
a. Between 500 and 600? the answer says 34.13% <<< how do you get to that???
b. Between 400 and 600?
Answer:
34.134%
68.268%
Step-by-step explanation:
Given that:
Mean (m) = 500
Standard deviation (s) = 100
Percentage between 500 and 600
P(500 < x < 600)
P(x < 600) - P(x < 500)
Z = (x - m) / s
P(x < 600)
Z = (600 - 500) /100 = 1
P(x < 500)
Z = (500 - 500) / 500 = 0
P(Z< 1) - P(Z < 0)
0.84134 - 0.5
= 0.34134
= 0.34134 * 100%
= 34.134%
B.) Between 400 and 600
P(x < 400)
Z = (400 - 500) /100 = - 1
P(x < 600)
Z = (600 - 500) / 500 = 1
P(Z< 1 ) - P(Z < - 1)
0.84134 - 0.15866
= 0.68268
= 0.68268 * 100%
= 68.268%
