Answer:
1260
Step-by-step explanation:
The least common multiple is the smallest positive number which is a multiple of the two. This means 84, 36, and 15 divide into it evenly. To find the multiple:
- We list the prime factors of each number.
- We note how many times each occurs.
- We multiply each factor the greatest number of times it occurs in a number.
84: 2*2*3*7
36: 2*2*3*3
15: 3*5
LCM: 2*2*3*3*5*7= 1260
Answer:
x= 42.5
Step-by-step explanation:
<AOB = 180°
Then <ACB = 180/2 = 90° (The angle subtended by an arc at the center is double the angle subtended by it at any point on the remaining part of the circle)
90 = 2x + 5
90-5 = 2x
85/2 =x
x= 42.5
Answer:
The value of z is -7
Step-by-step explanation:
To solve this problem, we will follow the step below;
1/4 z = -7/8 + 1/8 z
Subtract 1/8 z from both-side of the equation
1/4 z - 1/8 z = -7/8
2z - z /8 = -7/8
z/8= -7/8
Multiply both-side of the equation by 8
z/8 × 8 = -7/8 × 8
At the left-hand side of the equation 8 will cancel-out 8 leaving us with just z while on the right-hand side of the equation 8 will also cancel-out 8 leaving us with negative seven
z = -7
The value of z is -7
