P = 2d
d = 2n.....n = 1/2d
q = d - 3
since dimes is mentioned in relation to quarters, pennies, and the nickels, u would use d as ur variable
ur expression would be : d + (2d) + (1/2d) + (d - 3) = total amount of coins...then u would solve for d, the number of dimes. And once u know that, u can sub that answer back into ur original equations to find the number of pennies, quarters and nickels
Answer:
C
Step-by-step explanation:
LF//RO,
So angle TLF and angle TOR are congruent.
Angle TFL and angle TRO are congrurent.
Because the two pairs of angles are alternate angles.
So the two triangles are similar by AA corollary.
Answer:
Center = (-3, 7)
radius = 5
Step-by-step explanation:
x² + y² + 6x – 14y + 33 = 0
Put the equation in standard form:
(x - h)² + (y - k)² = r²
(h, k) is the center
r is the radius
---------------------------
Regroup
x² + 6x + y² - 14y = -33
Complete the square for x
(x + 3)² + (y - 7)² = -33 + 3² + (-7)²
(x + 3)² + (y - 7)² = 25
Center = (h, k) = (-3, 7)
radius = √25 = 5
-4x+2z=14
-2x-4z=22
y=x+z+12
-4x-x+2z-2z=14+11
-5x=25
x=-5
10-4z=22
-4z=12
z=-3
y=-5-3+12
y=4
Answer:
x=-5; y=-3; y=4
Answer:
3.5588 x 10⁸
Step-by-step explanation:
(3.1 x 10³) (1.148 x 10⁵) = (3.1 x 1.148) (10³ x 10⁵)
= 3.5588 x 10⁸
