Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
6x + 8y = 0
-7x + y = 31
Step 2: Rewrite Systems
-7x + y = 31
Add 7x to both sides: y = 7x + 31Step 3: Redefine Systems
6x + 8y = 0
y = 7x + 31
Step 4: Solve for x
Substitution
Substitute in y: 6x + 8(7x + 31) = 0Distribute 8: 6x + 56x + 248 = 0Combine like terms: 62x + 248 = 0Isolate x term: 62x = -248Isolate x: x = -4Step 4: Solve for y
Define equation: -7x + y = 31Substitute in x: -7(-4) + y = 31Multiply: 28 + y = 31Isolate y: y = 3please help ill mark brainliest if correct
The answer is A) (3.1, 2.2)
Answer:
A
Step-by-step explanation:
Given the 2 equations
y = 2x - 4 → (1)
2x + 4y = 15 → (2)
Substitute y = 2x - 4 into (2)
2x + 4(2x - 4) = 15 ← distribute and simplify left side
2x + 8x - 16 = 15
10x - 16 = 15 ( add 16 to both sides )
10x = 31 ( divide both sides by 10 )
x = 3.1
Substitute x = 3.1 into (1) and evaluate for y
y = 2(3.1) - 4 = 6.2 - 4 = 2.2
solution is (3.1, 2.2 ) → A

Answer:
length of each is 51
Step-by-step explanation:
they are congruent triangles so they are equilateral
therefore, you can set 7x - 5 and 5x + 11 equal to each other and solve for 'x'
2x = 16
x = 8
Substitute 8 into each expression and both come out to be 51

This formula gives the yearly depreciation D for
an item in terms of its cost C, its salvage value
S, and the number of years 71. Solve the
equation below for C.
C-S
De
Answer:
C = 71D + S
Step-by-step explanation:
The computation of the equation for C is as follows:
Given that
Yearly Depreciation = D
Cost = C
Salvage value = S
Number of years = 71
Based on the above information
The formula for the yearly depreciation i.e. D is
D = (C - S) ÷ 71
71D = C - S
71D + S = C
So, the equation would be
C = 71D + S

On considère les deux expressions A et B. A=4(x+5)-8 B=x au carré+15. Avec x=1,puis avec x=3, je trouve le même résultat pour A et B donc, quel que soit le nombre x, on a A = B. Emma a-t-elle raison ? Justifier la réponse.
Explication étape par étape:
Compte tenu des expressions ';
A = 4 (x + 5) -8
B = x² + 15
Nous devons vérifier si A = B pour les deux valeurs de x à x = 1 et x = 3
à quand x = 1
A = 4 (1 + 5) -8
A = 4 (6) - 8
A = 24-8
A = 16
B = x² + 15
B = 1² + 15
B = 1 + 15
B = 16
Donc à quand x = 1, A = B = 16
quand x = 3
A = 4 (x + 5) -8
A = 4 (3 + 5) -8
A = 4 (8) - 8
A = 32-8
A = 24
B = 3² + 15
B = 9 + 15
B = 24
Également lorsque x = 3, A = B = 24

Luna entered a raffle for a new pair of running shoes. She purchased 20 tickets and was told that she had a 20% chance of winning. How many tickets were sold? P (Luna winning) = StartFraction Number of tickets purchased over Total number of tickets sold EndFraction. 20 percent = StartFraction 20 over x EndFraction. One-fifth = StartFraction 20 over x EndFraction. x = tickets
Answer:
100 ticketsStep-by-step explanation:
Probability of winning = amount of tickets purchased/Total number of tickets
20% = 20/total number of tickets
20/100 = 20/total number of tickets
cross multiply
20 * total number of tickets = 20 * 100
20 * total number of tickets = 100
total number of tickets sold = 100 tickets
