Since line t is a transversal line all angle which are perpendicular with 63 will equal to the same value (63) and also line m is a straight line where it’s total will be 180
So,
3x + 2x + 63 = 180
5x + 63 = 180
5x = 180 - 63
5x = 117
Divide by 5 throughout
X = 23.4degrees
Answer:
D) the value of x is 135, because the angles shown in each diagram are complementary
Step-by-step explanation:
Each diagram has 2 angles labeled, and those two angles are always supplementary. The sum of the measures of two supplementary angles is 180°.
x + 45 = 180
x = 180 - 45
x = 135
Answer: D) the value of x is 135, because the angles shown in each diagram are complementary
Answer: 90
Step-by-step explanation:
In the number 73,951, the digit 9 is on the third position, so you need to put the number of the position minus one zeros before it: ( position number 3, 3 - 1 = 2, so we put 2 zeros)
the 9 in that digit represents a 900.
now, 1/10 times that number is:
900*(1/10) = 900/10 = 90
then the answer is 90.
In the number 90, the value represented by the 9 is equal to 1./10 times the value represented by the 9 in 73,951
Kenny can buy 15 t shirts and 3 sweatshirts.
Step-by-step explanation:
Given,
Number of members = 18
Cost of each t shirt = $9
Cost of each sweatshirt = $15
Money = $180
Let,
x be the number of t shirts
y be the number of sweatshirts
According to given statement;
x+y=18 Eqn 1
9x+15y=180 Eqn 2
Multiplying Eqn 1 by 9
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 6
Putting y=3 in Eqn 1
Kenny can buy 15 t shirts and 3 sweatshirts.
