1.2x + 7 - 5x
2.2c - 3 = 2(6 - c) + 7c
Answer:
2. 3/2 = 1.5. 3. 7. 5. 7/5 = 1.4. 4. 17. 12. 17/12 = 1.416666. 5. 41. 29. 41/29 = 1.413793. 1.3(c) 1.7(c). let P2k = Xk and q2k = 2Yk.
Step-by-step explanation:
-3.8x + 7 and c = -75/14 and/or c = -5.35714
Step-by-step explanation:First equation:
1.2x + 7 - 5x =
Step 1 - Group like terms:
1.2 - 5x + 7
Step 2 - Add simliar elements:
1.2 x - 5x = -3.8x =
3.8x + 7
Answer: -3.8x + 7
Second equation:
2.2c - 3 = 2(6 - c) + 7c =
Step 1 - Multiply both sides by 10:
2.2c ⋅ 10-3 ⋅ 10 = 2(6 - c) ⋅ 10 + 7c ⋅ 10
Step 2 - Refine:
22c - 30 = 20(6-c) + 70c =
- Expand 20(6-c): 120 - 20c
22c - 30 = 120 - 20c + 70c
Step 3 - Add similar elements:
-20c + 70c = 50c =
22c - 30 = 120 + 50c
Step 4 - Add 30 to both sides:
22c - 30 + 30 = 120 + 50c + 30
Step 5 - Simplify:
22c = 50c + 150
Step 6 - Subtract 50c from both sides:
22c - 50c = 50c + 150 - 50c
Step 7 - Simplify:
-28c = 150
Step 8 - Divide both sides by -28:
-28c/-28 = 150/-28
Step 9 - Simplify:
c = -75/14
Answer:
Fraction form: c = -75/14
Decimal form: c = -5.35714

The ratio of almond pieces to
cranberry pieces in a salad is 3 to 4.
If there is a total of 28 pieces in
salad, how many are almond pieces
and how many are cranberry
pieces?
Answer: There are 12 almonds and 16 cranberries.
Step-by-step explanation: This is a proportions problem.
If the ratio of almonds to cranberry is 3 to 4, that means for every 7 pieces, there are 3 almonds and 4 cranberries.If there are a total of 28 pieces, you need to multiply each piece of the original proportion by 4 (28/7 = 4).3 * 4 = 12 almonds4 * 4 = 16 cranberriesCheck: 12 + 16 = 28Answer:
There are 12 almond and 16 cranberry
Step-by-step explanation:
almond : cranberry : total
3 : 4 : 3+4 = 7
We know there are 28 pieces
28/7 = 4
Multiply each piece by 4
almond : cranberry : total
3*4 : 4*4 : 7*4
12 16 28
There are 12 almond and 16 cranberry

I think you do 27 divided by 6 then multiple whatever you get by 17
27 divided by 6= 4.5
X 17 = 76.5
Step-by-step explanation:
I think this is how... you find the amount you need for 1 cup flour then multiply by 17 since you now know the amount of honey needed for one cup flour

Function B is represented by this table of values:
Answer:
is it B ?
Step-by-step explanation:
i think this is it y=3x+10 y = 3 x + 10. Use the slope-intercept form to find the slope and y-intercept.
if u can answer these ill give brainliest
Answer:
Here is the answer it is in the step-by-step explanation:)
Step-by-step explanation:
11.b.) x^9=
x= 3
11.c) x^343=
x=7^7
12a.) 3^x=6
x=729
12b.) x^121

Which linear function has the greatest y-intercept? y = 6 x + 1 On a coordinate plane, a line goes through points (0, 2) and (5, 0). On a coordinate plane, a line goes through points (1, 2) and (0, negative 3). y = 3 x + 4.
Answer:
y = 6x + 1 (0,2) (5,0)
Step-by-step explanation:
Really just need to pay attention where the x coordinate is at. If at 0, and the y coordinate is elsewhere, you will be able to tell where the y intercept is. Usually, you quickly draw a graph if the numbers are more complex.
MODELING REAL LIFE Lightning strikes Earth 1000 times in 10 seconds.
a. How many times does lightning strike in 12 seconds?
Lightning strikes ? times in 12 seconds.
Question 2
b. How many seconds does it take for lightning to strike 7250 times?
It takes ? seconds for lightning to strike 7250 times.
Answer:
Didn't I answer this for you already?
a) 1200 times
b)72.5 seconds
Step-by-step explanation:
in one second it will strike 1000/10=100 times
so in 12 seconds it will strike 100x12=1200 times
Monica deposits $200 into a savings account that pays a simple interest rate of 3.3%. Paul deposits $300 into a savings account that pays a simple interest rate of 2.4%. Monica says that she will earn more interest in 1 year because her interest rate is higher. Is she correct? Justify your response.
Answer:
She is not because Paul deposited more money than her, which was enough so that he would earn more interest.
Step-by-step explanation:
Monica
i = prt
i = 200 * 0.033 * 12
(12 is represented as months)
Multiply.
i = 79.2
Paul
i = prt
i = 300 * 0.024 * 12
(you can choose months or years, but they have to be the same)
Multiply.
i = 86.4
Answer
Monica is wrong because Paul deposited more money than her, which was enough so that he would earn more interest.

Bottom one is the correct answer to the question
Step-by-step explanation:
Determine the lateral and total surface area of the pyramid.
Answer:
Lateral surface area = 45.5
Total surface area = 60.2
Step-by-step explanation: To find the lateral surface area, we first need to find the surface area of one triangle. For the triangle on the right/left, you multiply 3.5*5.8, which equals 20.3. Since this is a triangle, we multiply the product (20.3) by 1/2. The answer is 10.15. Since there are two triangles with the same dimensions as this, we multiply 10.15 by 2, which equals 20.3. For the triangle on the top/bottom, we multiply 4.2*6, which equals 25.2. Since this is a triangle again, we multiply 25.2 by 1/2. The answer is 12.6. Since there are two triangles with the same dimensions as this, we multiply 12.6 by 2, which equals 25.2. Now we add 20.3 + 25.2, which equals 45.5. This is the lateral surface area.
To find the total surface area, we now need to find the area of the base as well. To do so, we multiply 4.2 by 3.5, which equals 14.7. Now we add 45.5, the area of all the triangles, with 14.7, the area of the base. The answer is 60.2.
I hope this helps!
