Answer:
walnuts cost $2.50 per pound, chocolate chips cost $1.50 per pound
Step-by-step explanation:
let w be the cost of 1 pound of walnuts
and c be the cost of 1 pound of chocolate chips
then
2w + 12c = 23 → (1)
5w + 3c = 17 → (2)
multiplying (2) by - 4 and adding to (1) will eliminate c
- 20w - 12c = - 68 → (3)
add (1) and (3) term by term to eliminate c
(2w - 20w) + (12c - 12c) = 23 - 68
- 18w + 0 = - 45
- 18w = - 45 ( divide both sides by - 18 )
w = 2.5
substitute w = 2.5 into either of the 2 equations and solve for c
substituting into (1)
2(2.5) + 12c = 23
5 + 12c = 23 ( subtract 5 from both sides )
12c = 18 ( divide both sides by 12 )
c = 1.5
then
cost of 1 pound of walnuts is $2.50
cost of 1 pound of chocolate chips is $1.50

Answer:
16.25
Step-by-step explanation:
each rod is 6.5 and 5 of those are connected togther
meaning the total length of those 5 rods is 6.5 x 5 or 32.5
the problem says that the length of those 5 rods are cut in half and wants to the length of those half-cutted pieces
to do that, simply divide 32.5 (the length of 5 rods) by 2
(or you could multiply 32.5 with 1/2)
and you get 16.25

hey someone help what is 7/4 + (-4/7)
Answers
Answer: 1 5/28 or 33/28
Step-by-step explanation:
Ignore the addition sign because you have a negative, then find a common denominator: 28 then 4x7 is 28 multiply both sides of the fraction do that for both fractions then subtract the numerators and keep the denominator the same.
Answer:
1 5/28
Step-by-step explanation:
7/4 + -4/7
= 49/28 + - 16/28
= 33/28
= 1 5/28

What is the perimeter, in centimeters, of a rectangle with vertices located at (−17, 12), (8, 12), (−17, −5), and (8, −5)?

84 cm

425 cm
Thanks to every answer
Brainly to the most reliable answer and right one
Random answer ignored
Answers
Answer:
The perimeter of the rectangle is 84 cm.
Step-by-step explanation:
From X=-17 to X=8 is 25 cm.
From Y=12 to Y=-5 is 17 cm.
Therefore, the equation is 2(25) + 2(17) = 84
The perimeter of the rectangle is 84 cm.
To find the perimeter of the rectangle
We need to find the length and width of the rectangle first, and then use the formula for the perimeter, which is P = 2(l + w).
The length of the rectangle is the distance between the points (-17, 12) and (8, 12), which is 8 - (-17) = 25 units.
The width of the rectangle is the distance between the points (-17, 12) and (-17, -5), which is 12 - (-5) = 17 units.
Using the formula for the perimeter of a rectangle, we have:
P = 2(l + w) = 2(25 + 17) = 84 cm
Therefore, the perimeter of the rectangle is 84 cm.

b. Jason makes 12 dollars per hour and gets his pay reduced by $14, making his paycheck less than $198.

d. Jason makes 12 dollars per hour and gets a bonus of $14, making his paycheck less than $198.
Answers
Answer:
the answer is b
Step-by-step explanation:
Jackson gets 12 dollars an hour making that 12x and his pay is reduced by 14 so that would make it 12x(12 dollars an hour) - 14 (what's reduced). and if he has less than 198, b would be the only answer that works

Which angles are complementary to AFB? Select all that apply.
Answers
Answer:
Angle BFC
Step-by-step explanation:
When an angle is complementary to another angle, that means they sum to 90 degrees.
Angle EFD is vertical to Angle AFC, so they are congruent. Because angle EFD is 90 degrees, and angle AFC is congruent, it is also 90 degrees.
So, we see, angle AFB + angle BFC = 90 degrees.
Angle BFC is complementary to AFB
It may seem confusing that it says 'select all that apply', and we only pick one answer, but trust the math. I have been on IXL myself, and have seen that even though it says 'select all that apply', there may only be one answer.

Horizontal translation
Reflection across the y-axis
90° clockwise rotation
90° counterclockwise rotation
Answers
If it were a horizontal translation, it would’ve been going left to right, which it isnt.
If it were reflected over the y-axis, the points wouldve just been reflected over to the other side, which its also not.
The 90° counterclockwise rotation is simply going the wrong way, so the 90° clockwise rotation has to be the answer.
Hope this helps! :)
Answer:
90° clockwise rotation
Step-by-step explanation:
A horizontal translation would have left the shape pointing in the same direction.
A reflection across the y-axis would bring it to a quadrant that is not shown.
90 degree counterclockwise rotation would have again taken the shape to a quadrant that is not shown.
The other answer is also correct. Their reasoning may help you understand it better, because people learn in different ways. So, I encourage that you read that as well.
