Which system of linear equations has the ordered pair (4, –5) as a solution? 2 x minus 5 y = negative 30 and 7 x + 4 y = negative 19 6 x minus y = negative 29 and 8 x + 3 y = negative 17 3 x minus 2 y = 22 and 2 x + 9 y = negative 37 5 x minus 6 y = 49 and x + 8 y = negative 27

The ordered pair (4, -5) satisfies the equation
3x- 2y= 22
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
We have ordered pair (4, -5)
First equation, 2x - 5 y= -30
So, 2(4)- 5(-5)= 8 + 25= 33
Second equation,7 x + 4 y = -19
So, 7(4)+4(-5)= 28 -20= 8
Third equation, 6x - y= -29
So, 6(4) +5= 24+ 5 = 29
Fourth equation, 8 x + 3 y= -37
So, 8(4) + 3(-5)= 32 - 15 = 17
Fifth equation, 3x- 2y= 22
3(4)- 2(-5)= 12 + 10 = 22
sixth equation, 2x+ 9y = -37
2(4) + 9(-5)= -37
seventh equation, 5x- 6y= 49
5(4) - 6(-5)= 20 + 30 = 50
eight equation, x+ 8y= -27
4+ 8(-5)= -36

Answer:
138
Step-by-step explanation:
G + H = 180 {G, H are linear pair}
12x + 6 + 4x - 2 = 180
12x + 4x + 6 - 2 = 180
16x + 4 = 180
16x = 180 - 4
16x = 176
x = 176/16
x = 11
G = 12x + 6
= 12*11 + 6
= 132 + 6
= 138

1. On Monday, Sarah
started reading her book
that has 26 chapters. On
Monday, she read 9/26 of
her book. On Tuesday she
read 6/26 of her book. How
much does she have left to
read?
Answer:
Sara have 11 chapters left to read.
Step-by-step explanation:
Total chapters Book has = 26
On Monday Sarah read = [tex]\frac{9}{26}\ of \ 26 \ chapters = \frac{9}{26}\times \ 26 \ chapters=9 \ chapters[/tex]
On Tuesday Sarah read = [tex]\frac{6}{26}\ of \ 26 \ chapters = \frac{6}{26}\times \ 26 \ chapters=6 \ chapters[/tex]
Total Chapters read by Sarah = [tex]9+6= 15 \ chapters[/tex]
Chapters left to read by Sarah = [tex]26-15 = 11 \ chapters[/tex]
So, Sara have 11 chapters left to read.
If the Miami Marlins won 14 of their first 27 games and the team continued to win at the
same rate, how many games would they win in a 162-game season?
c. 98 games
d. 56 games
a. 84 games
b. 70 games
This type of problem can be solved in various ways such as in terms of ratios and fractions, Let us go with fractions.
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, Miami Marlins won 14 of their first 27 games.
So, their win rate in decimal is,
= 14/27.
= 0.518.
∴ In 162 games at the same rate, Miami Marlins will win,
162×0.518.
= 84 games.
So, after playing 162 games they'll win 84games.

Find the multiplies of 2
A varies inversely as the square of B. If A is 1 when B is 3, find A when B is 5
Answer:
0.36
Step-by-step explanation:
A= K/B^2
K= A × B^2
K= 1 × 3^2
K= 1×9
K= 9
Therefore if B is 5 then A can be calculated as follows.
K= A × B^2
9= A × 5^2
9= A × 25
9= 25A
A= 9/25
A= 0.36
Hence A is 0.36

find the measure of BE step by step
Answer:
BE = 49 cm
Step-by-step explanation:
Use Pythagorean theorem
(hypotenuse)² = (base)² + (leg)²
ΔDEF,
DE² + EF² = FD²
DE² + 63² = 65²
DE² + 3969 = 4225
DE² = 4225 - 3969
DE² = 256
DE = √256 = √(16*16)
DE = 16 cm
ΔCBD,
BC² + BD² = CD²
56² +BD² = 65²
3136 + BD² = 4225
BD² = 4225 - 3136
BD² = 1089
BD = √1089 = √(33*33)
BD = 33 cm
BE = BD + DE
= 33 + 16
BE = 49 cm
