Answer:
6 pictures
Step-by-step explanation:
Let x be the number of pictures that was bought
Let y be the total amount of money collected for the picture
y= 3.25+12.75
3.25+12.75x= 79.75
Therefore x can be calculated as follows
12.75x= 79.75-3.25
12.75x= 76.5
x= 76.5/12.75
= 6
Hence Joshua ordered 6 pictures
Answer:
4x² (3x - 1)
Step-by-step explanation:
→ Find the LCM of 12 and 4
LCM = 4
→ Find the LCM of x³ and x²
LCM = x²
→ Combine both LCM's together to form the outside multiplier
4x² (? - ?)
→ Complete the operations of 12x³ ÷ 4x² to find the first ? and 4x² ÷ 4x² to find the second ?
12x³ ÷ 4x² = 3x
4x² ÷ 4x² = 1
→ Therefore,
∴ 4x² (3x - 1)
Answer:D
Step-by-step explanation:it’s a supplementary angle which measures 180 degree now subtract side T=79 degrees by the 180 degree= 101
Answer:
D
Step-by-step explanation:
given a quadratic equation in standard form
ax² + bx + c = 0, then the discriminant is
Δ = b² - 4ac
x² + 3x - 4 = 0 ← is in standard form
with a = 1, b = 3, c = - 4
b² - 4ac = 3² - (4 × 1 × - 4) = 9 - (- 16) = 9 + 16 = 25 → D
