Mahni plans to spend the next 12 weeks saving some of her income. She will save $x a week for the first 6 weeks and then $(2x − 30) a week for the following 6 weeks. If she managed to save $213 in the first six weeks, how much did she save in total over 12 weeks? Explain correctly how to do this to get Brainliest ANSWER

Answer:

Step-by-step explanation:A = 30 given

C = 90 given

B = 180 -30-90 = 60 triangle angles add up to 180

Answer:

Try 4/6

Answer:

22°

Step-by-step explanation:

this is a right angle. right angles = 90°. you can now subtract 90-68 to give you 22.

Answer:

-x

Step-by-step explanation:

Note that when there is a standalone variable (such as the x in this example), it typically actually means 1x. (If it is -x, it will be -1x.) However, you do not write 1 in front, as it is presumed.

Subtract the coefficient of each terms:

1x - 2x = -1x

-x is your simplified form.

===========================================

Work Shown:

4x^2 - y^2

(2x)^2 - (y)^2

(2x-y)(2x+y)

When going from the second step to the third step, I used the difference of squares rule. That rule is a^2-b^2 = (a-b)(a+b). In this case, a = 2x and b = y.

Side note: (2x-y)(2x+y) is the same as (2x+y)(2x-y). We can multiply in any order.

Answer:

- 3, - 2, - 1 and 6

Step-by-step explanation:

To find the first 3 terms, substitute n = 1, 2, 3 into the nth term rule

a₁ = 1 - 4 = - 3

a₂ = 2 - 4 = - 2

a₃ = 3 - 4 = - 1

The first 3 terms are - 3, - 2, - 1

similarly substitute n = 10 into the rule for 10th term

a₁₀ = 10 - 4 = 6

[tex]5(3q - 1)5q + 15 \\ 15q - 5 \times 5q + 15 \\ 15q - 25q + 15 \\ - 10q + 15 \\ - 5(2q - 3) \\ [/tex]

Answer:

Daniiel is 33 years old.

The son is 7 years old.

Step-by-step explanation:

x+26=3x

The x represents the son.

To solve for x:

-26=x-3x

-26=-2x

x=13

Since the father will be 3 times his son's age in six years we subtract 6.

x=7

This means the son is 7 years old as of right now. To find the father's age you do 7+26=33

Answer:

A temperature rise of 5°C

Step-by-step explanation:

Because there is no negative/minus sign in front of 5°C, it can be assumed that the value is positive.

Therefore, if 5°C is positive, it means that the temperature is increasing or rising by 5°C.

Answer:

x=-1/25

Step-by-step explanation:

-3/5x=15

-3/5x(5x)=15(5x)

-3=75x

75x=-3

x=-3÷75

=-3/75

=-1/25

Answer:

a

Step-by-step explanation:

most likely the answer is a because we have (10,4), 10 being the domain(X-Intercept) and 4 being range(Y-Intercept)

if we substitute the value of X in option a with 10, we get a value of 3.7 as shown in the picture which can be can be converted to 4

12 CLASSES  10.00=120.00 PLUS 1 MAT FOR 19.95 FOR A TOTAL OF 120.00+19.95=139.95 THUS WE HAVE 12 CLASSES + 1 MAT

Step-by-step explanation:

12 CLASSES  10.00=120.00 PLUS 1 MAT FOR 19.95 FOR A TOTAL OF 120.00+19.95=139.95 THUS WE HAVE 12 CLASSES + 1 MAT

Answer:

x=33°

Step-by-step explanation:

(x-1)+x=x+32 (ext angle of a triangle)

x-1+x=x+32

x+x-x=32+1

x=33

Answer:

i) no. of students like none of subject = 5

total no. of students= 69

=> no. of students like at least one subject= 60-5

= 55

ii) no. of students like math only = 15

no. of students like science only = 20

total no. of students like only one subject= 35

no. of students like none subject = 5

=> no of students like both the subjects = 60-(35+5) =20

(iii) no. of students like math= 15+ 20

= 35 ( because 15 like math only and 20 like both)

(iv) no. of students like science= 20+20

= 40 ( because 20 like science only and 20 like both )

Step-by-step explanation:

Answer:

35 kids.

Step-by-step explanation:

55 kids who like math or science

15 math only and 20 science only

s0 20 who like both math and science

so 35 kids who like math
