Answer:
Step-by-step explanation:
-(3x-7)=43.
Distribute the negative properly
-3x+7=43
Then subtract 7 from both sides
-3x=36
Then divide by -3 to get your answer
x=-12
What type of triangle has an exterior angle that is obtuse at two vertices? Explain your reasoning.
Answer:
A right triangle
Step-by-step explanation:
A right triangle would meet these characteristics. A triangle's inner angles always add up to be 180 degrees. A right triangle has one angle at 90 degrees meaning the other two angles need to be less than 90 degrees and sum up to be 90 degrees. This would indicate that both of these angles' exterior angles would be obtuse because they would be wider than 90 degrees.

Answer:
a ( copper and nickel
b ( 1034.9
Step-by-step explanation:
Add all the values of melting points
2,651 + -37.89 = 2613.11
2613 + -458 = 2155.11
2155.11 + 1984.32 = 4139.43
Divide the number by the number of numbers: 4139.43/4 = 1034.8575
1034.8575 rounded to the nearest tenth is 1034.9, thats how you find the mean, or the average.

Step-by-step explanation:
Dwight is making accessories for the soccer team. He uses 648.62 inches of fabric on headbands for 39 players and 2 coaches. He also uses 331.89 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answer:
24.33 inches
Step-by-step explanation:
inches of fabric on headbands = 648.62 inches
39 players and 2 couches = 41 people
Inches of fabrics per person = Total headbands inches / number of people
= 648.62 inches / 41
= 15.82 inches per person
Inches of fabrics used for headbands per person = 15.82 inches
inches of fabric on wristbands = 331.89 inches
Used for players alone
Inches of fabrics for wristband pee person = Total inches of fabrics for wristband / number of people
= 331.89 inches / 39 players
= 8.51 inches
Inches of fabrics used for wristband per person = 15.82 inches
How much fabric was used on a headband and wristband for each player?
= Inches of fabrics used for headbands per person + Inches of fabrics used for wristband per person
= 15.82 inches + 8.51 inches
= 24.33 inches
Inches of fabrics used on headband and wristband for each player is 24.33 inches

Step-by-step explanation:
What is y – 3 = 7 (x – 5) in standard form?
Answer:
38=7x-y
Step-by-step explanation:
standard form= Ax+By+C
(y-3=7(x-5))
(y-3=7x-35)+3 to both sides
(y=7x-38) +38 to both sides
(y+38=7x) -y to both sides
38=7x-y
you have to move the 38 and y because if you moved the x value, than A becomes negative and it can't be in standard form
Answer:
7x-y=32

When naming angles, it is typical to use one or three letters. Sometimes one cannot use one letter. When using three letters, the ________ must be the letter in the middle. Other times one uses numbers to name the angles.
Answer:
angle
Step-by-step explanation:
The point that the two rays intersect is called the angleThe two rays are called the sides of the angleWhen naming angles, it is typical to use one or three letters. Sometimes one cannot use one letter. When using three letters, the angle must be the letter in the middle. Other times one uses numbers to name the angles as below.Name an angle using one letter. <AName three different angles. <A, <R, <I<IRC can also be named in what two other ways? <I, <CRIName the points on the interior of <FAB: S, T, R, FName the points on <FAB: F, A, B, YChoose the equation that represents the line that passes through the point (6, −3) and has a slope of one half
Answer:
y = 1/2x - 6
Step-by-step explanation:
slope = 1/2 = m
lets find your y-intercept using slope intercept form: y = mx + b using the points they gave us (6, -3)
y = mx + b; plug what we know to find b, which is our y-intercept.
-3 = 1/2(6) + b
-3 = 3 + b
-6 = b
Now you have all you need to write your equation
y = mx + b
y = 1/2x - 6

2. The value of y varies directly with x. When y = 45, x = 4. What is the
value of y when x is 7?
Answer:
direct variation means y=kx (inverse variation is yx=k or y=k/x)
so we are given that:
75=k/2, so k=150 which means:
y=150x now
y(2.25)=150(2.25)=337.5
