Sandra and Peter together weigh 275 pounds. Sandra and
Martin together weigh 245 pounds. All three together
weigh 410 pounds. What is Sandra's weight alone?
Answers
Answer:
110 pounds
Step-by-step explanation:
Let the weight of Sandra, Peter and Martin be S, P and M pounds respectively.
S +P= 275 -----(1)
S +M= 245 -----(2)
S +P +M= 410 -----(3)
(3) -(1):
S +P +M -(S +P)= 410 -275
S +P +M -S -P= 135
M= 135
Substitute M= 135 into (2):
S +135= 245
S= 245 -135
S= 110
Thus, Sarah weighs 110 pounds.

Find the perimeter of an isosceles triangle. The base is 3y and each side is (0.6y-7).
Answers
Answer:
Perimeter = 4.2y - 14
Step-by-step explanation:
Perimeter of a triangle = the sum of the three sided of the triangle.
In an isosceles triangle, there are two equal sides and a base.
Perimeter = (0.6y - 7) + (0.6y - 7) + 3y
Perimeter = (0.6y + 0.6y + 3y) - 7 - 7
Perimeter = 1.2y + 3y - 14
Perimeter = 4.2y - 14
Find (fog)(x) (gof)(x), if f(x) = 1 - 5x; g (x) = |2x + 3| x
Answers
Step-by-step explanation:
f (x) = 1 - 5x
g (x) = 2x + 3
find (fog) (x)
it's a composite function so basically we substitute x = 2x + 3 where we see x in f (x) = 1 - 5x
so doing that we'll get
1 - 5(2x + 3)
next expand your brackets
1 - 10x + 15
equate to 0 to make things easier
1 - 10x + 15 = 0
make x the subject
1 + 15 = 10x (this is the same as 10x = 1 + 15)
x = 16/10 (you can leave it as a fraction)
fog(x) = 16/10
find gof (x)
we'll do the same thing again
2(1-5x) + 3
2 -10x + 3 = 0
2 + 3 = 10x
10x = 5
x = 5/10 (reduce)
x = 1/2
gof (x) = 1/2

pls I need help
Answers
Answer:
A) a = 4
B) m = 2
Step-by-step explanation:
A) 2a + 7 = 15
2a + 7 - 7 = 15 - 7
2a = 8
2a/2 = 8/2
a = 4
B) 4m - 6 = 2
4m - 6 + 6 = 2 + 6
4m = 8
4m/4 = 8/4
m = 2
Answer:
a = 4 and m = 2.
a) Find the value of a if the total of a being doubled and added to 7 is 15.
b) Find the value of m if the total of m being multiplied by 4 and being subtracted by 6 is 2.
Step-by-step explanation:
2a + 7 = 15
→ Minus 7 from both sides
2a = 8
→ Divide both sides by 2
a = 4
4m - 6 = 2
→ Add 6 to both sides
4m = 8
→ Divide both sides by 2
m = 2

========================================================
Explanation:
Angles A and B are supplementary which mean they combine to form a straight line. This further means the angles add to 180.
A+B = 180
(8x-27) + (4x+3) = 180
(8x+4x) + (-27+3) = 180
12x-24 = 180
12x = 180+24
12x = 204
x = 204/12
x = 17
Use this x value to find angles A and B
A = 8x-27 = 8*17-27 = 109B = 4x+3 = 4*17+3 = 71Note how A+B = 109+71 = 180 to help verify the answer.
Answer:
109
Step-by-step explanation:
supplementary angles equals 180 degrees
8x-27+4x+3=180
12x-24=180
12x=204
x=17
Then you put the 17 where the x is
8(17)-27=109
