Is Has two congruent sides?
Yes. When you subtract two, you get two congruent sides.
What Four consecutive odd integers whose sum is -220?
Let x be the smallest of the consecutive odd integers. Since consecutive odd integers differ by 2, we havex + (x + 2) + (x + 4) + (x + 6) = -2204x + 12 = -220 (subtract 12 to both sides)4x = -232 (divide by 4 to both sides)x = -58Thus, the four consecutive odd integers whose sum is -220 are -58, -56, -54, and -52.
What is the sum of two consecutive integers is 237?
Algebraically, X = integers. X + (X + 1) = 237 gather all terms on the left 2X + 1 = 237 subtract 1 from each side 2X = 236 divide both sides integers by 2 X = 118 --------------so, X + 1 = 119 ----------------so, The two consecutive integers that = 237 are 118 and 119 -------------------
How do you spell scalene?
That is the correct spelling of "scalene" (in one sense a triangle with three dissimilar sides).
What is 2x plus 22 equals x?
2x + 22 = x Subtract x from both sides: x + 22 = 0 Subtract 22 from both sides: x = -22
How do you solve 3x-7 equals 5x plus 3?
First you subtract 3x from both sides and get -7=2x+3. Then subtract 3 from both sides and get -10=2x. Then divide both sides by 2 and x=-5.
What is 9y plus 4 equals 2y plus 25?
9Y + 4 = 2Y + 25 subtract 2Y from both sides 7Y + 4 = 25 subtract 4 from both sides 7Y = 21 divide both sides integers by 7 (7/7)Y = 21/7 Y = 3 -----------------check in original equation 9(3) + 4 = 2(3) + 25 27 + 4 = 6 + 25 31 = 31 ---------------checks
How do you find the number of diagonals in a shape?
you subtract 3 from the number of sides then multiply that by the number of sides divided by 2
What kind of quantities can be added or subtracted from both sides of an equation?
You can add or subtract any quantity on both sides of an equation, without changing the equation's solution set. Just make sure you add or subtract the same thing on both sides.
How would you solve 70 equals 81 - n?
70 = 81-n subtract 70 from both sides 0 = 11 - n subtract 11 from both sides -11 = -n divide both sides by -1 11 = n
What is the solution to 5x plus 36 equals x?
5x + 36 = x Subtract x from both sides: 4x + 36 = 0 Subtract 36 from both sides: 4x = -36 Divide both sides by 4: x = -9
Three times the first of three consecutive odd integers is three more than the twice and the third What is the average of the three integers?
Let the first of the three odd consecutive integers be x, so that the second of these integers would be x + 2, and the third one would be x + 4. We have: 3x = 2[(x + 2)+ (x + 4)] + 3 3x = 2(2x + 6) +3 3x = 4x + 12 + 3 (subtract 4x to both sides) -x = 15 (multiply by -1 to both sides) x = -15 (the first one) So the integers are -15, -13, and -11. The average of those integers is (-15 + -13 + -11)/2 = -39/2 = -19.5.
