Answer:
it's simple substitution
Step-by-step explanation:
1. (7)(2)/2= 14/2=7
2. (5)-(8)/4=
3. (6)-(1)+6=11
4. (19)+(1)^3=21
Answer:
4/3
Step-by-step explanation:
Answer:
You CAN do it. triangle with the circle. find area of triangle first and subtract circle. (8*8)/2 = 32. minus circle. (2.5*pi^2) = 24.674011. so we have 32 - 24.7 (rounded) = 7.3 for triangle. as for the other? divide it into segments. we have a rectangle on bottom followed by 2 triangles on top of that rectangle. Recangle height is 2 * width. The width is 8 as we can see the top. 2*8= 16. plus the triangles. we know the triangle height is 6 minus the 2 from the rectangle height so 6-2=4 times the width which is the rectangle width minus the 6 from the middle divided by 2 because there are 2 triangles. 8-6=2/2 = 1. height * width = 4 divide by 2 = 2. that is the area of one triangle. but because there are 2 triangles multiply by 2. 2*2 = 4. 16+4=20 for the area of the second figure.
Step-by-step explanation:
Answer: 84/96 and 40/96
Step-by-step explanation: You find a denominator that they both have in common. The LCM is 96 and you get the answer! You multiply 1 side by 8 and the other by 12 and you get the answer!
