Pls help I can't do anything I will give the brain thingy

Sidana [21]

Step-by-step explanation:

Blank C :

Given total = 68

No. of TV news = 13

Therefore, in Internet it would be = Total - TV news

= 68 - 13 = 55 (ans)

Blank D :

No. of Internet news in 7th grade = 55

No. of Internet news in 8th grade = 64

Hence, total Internet base news = 64 + 55 = 119 (ans)

Blank B :

All total = 138

Internet news total = 119

Hence, TV news total = All total - Internet news

= 138 - 119 = 19 (ans)

Blank A :

No. of TV news in 7th grade = 13

Total news in TV = 19

Therefore, no. of TV news in 8th grade = 19 - 13 = 6(ans)

Blank E :

All total = 138

Total of 7th grade news = 68

Hence, total of 8th grade news = 138 - 68

= 70 (ans)

Pls help?!?!?!?!?!??!!

Answer:

m<A = 120°

m<C = 45°

Step-by-step explanation:

We can use the triangle sum theorem to find the measures of the angles.

m<A + m<B + m<C = 180°

Then substitute in their given values.

12x + 12 + 15 + 3x + 18 = 180°

Now simplify the equation and you get

15x + 45 = 180°

Continue to solve

15x = 135

x = 9°

Now substitute this value of 9 for the angle expressions of <A and <C

(12 x 9) +12 = m<A

m<A = 120°

(3 x 9)+ 18 = m<C

m<C = 45°

Hope this helps. To check your answer you can add up all the answers to see if it equals 180°.

May someone help me with this?

elena-14-01-66 [18.8K]

I am putting this into rows. Ex: row one has 0. row two has blank and seven.

1: 0

2: 9 7

3: - 9 6

4: 1 3

5: - 1 2

6: 1

So the answer on top would be 8 1 r 1.

Brandy is trying to factor the quadratic $3x^2 - x - 10.$ She starts by assuming that the quadratic factors as \[3x^2 - x - 10 =

taurus [48]

Answer:

(B , D) = (-2,5)

Step-by-step explanation:

The given quadratic expression is

$3x^{2} -x-10$

compare the given expression with $ax^{2} +bx+c$

so we have $a = 3 , b = -1 ,c = -10$

now $ac=3 (-10)=- 30$ and $b= -1$

we need to find two numbers such that their product is -30 and sum is -1

-6 and 5 are such numbers

so we have

$3x^{2} -6x+5x-10$

grouping first two terms and last two terms

$(3x^{2} -6x)+(5x-10)$

factor out 3x from first two terms and 5 from last two terms

$3x(x-2) +5(x-2)$

$(x-2)(3x+5)$ ( factor out (x-2))

$(x+(-2))(3x+5)$

hence B =-2 and D= 5

(B,D)= (-2,5)

The sum of a number and three is less than twelve

Rasek [7]

Answer:

Equation: x+3<12 Answer: x<9

Step-by-step explanation:

SO bascially what you do is you find the equation based on the wording (The sum of a number and three is less than twelve) and after you find the equation (which is x+3<12), you subtract 3 from both sides, getting x<9

Hope this helps:)
