x/9+14=(-45). Find the value of x.
The value of x is (-531) because x/9=(-59) and -59X9=-531.
100
What is 4+5X6-(3-1)?
It is 32 because 4+30-(2)=34-2=32.
100
What type of shape is this? It has angles of 51°, 51° and 78°.
It is a triangle because it has 3 angles.
100
Simplify 182:26.
The simplest ratio is 7:1 because 182/26=7 and 26/26=1.
100
The lengths of a triangle are 2, 5 and 1. Is this possible?
-_-" no it is not. 2+1<5, so therefore this triangle is not possible.
200
Find the pattern. 1, 11, 34, 77.
The pattern is (Y+4)2+1.
200
Find the expanded form of 112582683457.
The expanded form is 100000000000+10000000000+2000000000+500000000+80000000+2000000+600000+80000+3000+400+50+7.
200
What type of angle is this? 191°
It is a reflex angle.
200
Find the percentage: 82/132.
The percentage is 62.121212......% because 82/132X100=62.12121212....... 62% is also acceptable.
200
If 2 of the lengths in a right triangle are 3 and 4. What is the length of the hypotenuse?
The length is 5 because the square root of 3X3+4X4=5.
300
49/7=56/X. Find the value of X.
X is 8 because 49/7=7 and 56/8=7.
300
Estimate 1.9126547579X9.278836548273456
The answer is 20 since you can round 1.9126547579X9 to 2 and 9.278836548273456 to 10, and 2X10=20.
300
In a triangle, what do the 3 angles add up to?
The 3 angles ALWAYS add up to 180°.
300
Find the matching fractions. 1/3, 7/4, 9/12, 8/13, 2000/1003, 91/203, 11/111 and 71/213.
The matching fractions are 1/3 and 71/213. 71/71=1 while 213/71=3.
300
What is the volume of a rectangular prism with side lengths 5, 27 and 0.27?
The volume is 36.45 since 5X27X0.27=36.45.
400
X+X+120=180. Find the value of X.
The answer is 30 since (180-120)/2=30.
