Answer:
x = 29
Step-by-step explanation:
Follow the directions: substitute 13 for y in the first equation.
x + 13 = 42
Subtract 13 from both sides of the equation.
x +13 -13 = 42 -13
x = 29
15376
/ I
961 16
/ I / I
31 31 4 4
31 × 4 = 124
The square root of 15376 is 124
Direct variation has the form y=kx. Given a point we can solve for the constant k.
y=kx, when y=9 and x=-3 becomes:
9=-3k
k=-3 so the constant of variation is negative 3
Answer:
2.8
Step-by-step explanation:
hypotonus is the longest edge of any triangle;
here the tallest edge equals the root of 8
the root of 8 = 2.83
Answer:
14n
Step-by-step explanation:
n - beads for each necklace , (6n) - beads for 6 necklaces
(2/3)n - beads for each bracelets, 12*(2/3)n=8n - beads for 12 bracelets
Altogether = 6n + 8n = 14n
