Answer:

1) m<1 = 25

2) m<4 = 155

3) m< 5 = 25

4) m<7 = 25

5) 110

6) 30.5

7) 74

Step-by-step explanation:

x + 155 = 180

x = 25

<4 = 155 because of vertical angle thm

<5 = 25 (congruent to <1) b/c of corresponding angles thm

<7 = <5 (25) because of vertical angles thm

5x + 15 = 8x - 42

-3x = -57

x = 19

5(x) + 15

5(19) + 15 = 110

180 - 110 = 70

3x + x + 4 + 70 = 180

4x + 74 = 180

4x = 106

x = 26.5

x+ 4 = 30.5

180 - 115 = 65

x + 4 + 2x + 65 = 180

3x + 69 = 180

3x = 111

x = 37

2x = 74

At the grocery store, Victor has narrowed down his selections to 88 vegetables, 66 fruits, 66 cheeses, and 77 whole grain breads

frosja888 [35]

Answer: There are 50388 ways to choose.

Step-by-step explanation:

Since we have given that

Number of vegetables = 8

Number of fruits = 6

Number of cheeses = 6

Number of whole grain breads = 7

Number of items he buys = 15

We need to find the number of ways he wants all 8 vegetables.

So, it becomes,

$^8C_8\times ^{19}C_7\\\\=1\times 50388\\\\=50388$

Hence, there are 50388 ways to choose.

Prove that there are no solutions in integers x and y to the equation 2x^2 + 5y^2 = 14

iren [92.7K]

Solve the equation for y using the formula for slope: y + mx + b

2x^2 + 5y^2 = 14
5y^2 = -2x^2 + 14
y^2 = -2/5x^2 + 14/5
y = the sq root of -2x^2/5 + 14/5

There is no integer solution to the square root of a negative number.
