Answer 1

Step-by-step explanation:

Number 1

180° = x + 70° + 55° + 30°

180° = x + 155°

x = 180° - 155°

x = 25°

Number 2

x° = 93°

y° = 47°

z° = 180° - 47° - 93°

z° = 180° - 140°

z° = 40°

Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. He spent a total of $47.65. Let m represent the number of magazines and b represent the number of books. Which equation models the situation?

Answers

Answer:

3.95m + 8.95b = 47.65

Step-by-step explanation:

Since Hugh paid $3.95 for every magazine, m would be multiplied by 3.95

Since he also paid $8.95 for every book, b would be multiplied by 8.95

All of this will eventually add up to a sum of 47.65

Q3). 0.4x + 0.3y = 1.7
0.7x - 0.2y = 0.8
Solve it by using substitution method.​

Answers

[tex]▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ { \huge \mathfrak{Answer}}▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ [/tex]

The values of :

[tex]x = 2[/tex]

[tex]y = 3[/tex]

The given equations are :

[tex]0.4x + 0.3y = 1.7[/tex]

[tex]0.7x - 0.2y = 0.8[/tex]

now, let's multiply both the equations with 10 on both sides.

so, now our equations will be :

[tex]4x + 3y = 17[/tex]

[tex]7x - 2y = 8[/tex]

from Equation second :

[tex]7x - 2y = 8[/tex]

[tex]2y = 7x - 8[/tex]

[tex]y = \dfrac{7x - 8}{2} [/tex]

now, let's substitute the value of y from here into Equation first.

[tex]4x + 3y = 17[/tex]

[tex]4x +3 \bigg ( \dfrac{7x - 8}{2} \bigg) = 17[/tex]

[tex]4x + \dfrac{21x - 24}{2} = 17[/tex]

[tex] \dfrac{8x + 21x - 24}{2} = 17[/tex]

[tex] \dfrac{ 29x - 24 }{2} = 17[/tex]

[tex]29x - 24 = 34[/tex]

[tex]29x = 34 + 24[/tex]

[tex]29x = 58[/tex]

[tex]x = \dfrac{58}{29} [/tex]

[tex]x = 2[/tex]

here, we got the value of x = 2, let's plug it in equation second to find value of y :

[tex]7x - 2y = 8[/tex]

[tex]7(2) - 2y = 8[/tex]

[tex]14 - 2y = 8[/tex]

[tex]2y = 14 - 8[/tex]

[tex]2y = 6[/tex]

[tex]y = \dfrac{6}{2} [/tex]

[tex]y = 3[/tex]

And value of y = 3
