Answer:
(-2,-7)
alternatively
x: -2
y: -7
Solve the two-step equation and identify the steps.
2= -7/4 + 1/4x
1. Add 7/4 to both sides
2. Multiply both sides by 4.
The solution is 15.
Answer:
x = 15
Step-by-step explanation:
Given
2 = - [tex]\frac{7}{4}[/tex] + [tex]\frac{1}{4}[/tex] x
Multiply through by 4 to clear the fractions
8 = - 7 + x ( add 7 to both sides )
15 = x

Answer: C
Step-by-step explanation:
Okay first set a comparison since the two triangles are similar
x-1/20=x-1+27/3x+8
x-1/20 = x+26/3x+8
cross multiply
20x+520=3x^2+8x-3x-8
3x^2-15x-528=0

1-4x/2x+1=4/1-5x
solve in quadratic equations
Answer:
I can only assume that the entire 1-4x is divided by 2x, and 4 by all of 1 - 5x. You can guarantee more accurate results by using brackets where appropriate. If I read that expression with the correct notation, it reads as [tex]1 - \frac{4x}{2x} + 1 = \frac{4}{1} - 5x[/tex].
Assuming instead that it's meant as [tex]\frac{1 - 4x}{2x + 1} = \frac{4}{1 - 5x}[/tex], we can solve it as shown below, giving us x values of 1 and 3/20 (or 0.15).
Step-by-step explanation:
First let's reformat this to the usual ax² + bx + c format:
[tex]\frac{1 - 4x}{2x + 1} = \frac{4}{1 - 5x}\\(1 - 4x)(1 - 5x) = 4(2x + 1)\\1 - 5x - 4x + 20x^2 = 8x + 4\\20x^2 - 5x - 4x - 8x + 1 - 4 = 0\\20x^2 - 17x - 3 = 0[/tex]
Let's solve it with the quadratic formula:
[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}\\\\x = \frac{17 \pm \sqrt{-17^2 - 4\times 20 \times( -3)} }{2\times20}\\\\x = \frac{17 \pm \sqrt{289 + 240} }{40}\\\\x = \frac{17 \pm 23 }{40}\\\\x = 1, \frac{3}{20}[/tex]

Carl is making accessories for the soccer team. He uses 666.96 inches of fabric on headbands for 39 players and 3 coaches. He also uses 333.06 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answer:
The amount of fabric was used on :
a) headband for each player = 15.88 inches of fabric
b) wristband for each player = 8.54 inches of fabric
Step-by-step explanation:
From the above question, we were told:
For headbands
Carl is making accessories for the soccer team. He uses 666.96 inches of fabric on headbands for 39 players and 3 coaches.
Total number of persons = 39 players + 3 coaches = 42 persons
42 persons = 666.96 inches
1 person = x
Cross Y
42x = 666.96 inches
x = 666.96 inches/42
x = 15.88 inches
For wristbands
He also uses 333.06 inches of fabric on wristbands for just the players.
We have 39 players
Hence:
39 players = 333.06 inches
1 players = x
Cross Multiply
39x = 1 × 333.06 inches
x = 333.06 inches/3
x = 8.54 inches
The amount of fabric was used on :
a) headband for each player = 15.88 inches of fabric
b) wristband for each player = 8.54 inches of fabric

[tex]\huge\boxed{\sf \frac{-16}{147} }[/tex]
Step-by-step explanation:
Multiplicative Inverse of [tex]\sf 3\frac{1}{2} (\frac{7}{2} )[/tex] = [tex]\sf \frac{2}{7}[/tex]
Multiplicative inverse of any number is the reciprocal of that number.
Additive inverse of [tex]\sf 2\frac{5}{8}(\frac{21}{8} )[/tex] = [tex]\sf -\frac{21}{8}[/tex]
Additive Inverse of any number is the number that has the opposite sign.
Solution:
[tex]\sf \frac{2}{7} / - \frac{21}{8} \\\\\frac{2}{7} * - \frac{8}{21} \\\\= \frac{2*(-8)}{7*21} \\\\= \frac{-16}{147} \\\\\rule[225]{225}{2}[/tex]

Which facts could be applied to simplify this expression? Check all that apply.
5 x + 3 y + (negative x) + 6 z
Answer:
The answer is B, C, and D. Like terms are terms with all the same variable, so 5x and -x are like terms.
C is correct. If we add -x to 5x, we get 4x. The other numbers remain unchanged because they have no like terms.
D is correct. Applying the rule of like terms, which is that like terms are numbers with the same variable, only add together numbers with the same variable.
