Something not being equal
Answer:
11 and 7
Step-by-step explanation:
let x be the bigger number and y the smaller
the sum of the two numbers is 18
x+y=18
x=18-y------i
the sum of the greater number and twice the smaller number is 25
x+2y=25----ii
substituting i in ii
18-y+2y=25
collecting like terms
y=25-18
y=7
subtitute for y in i to get x
x=18-y
x=18-7
x=11
Answer:
y = 4/3
x = 2
Step-by-step explanation:
2x − 3y = 2
x = 6y − 5
x - 6y = -5
2x − 3y = 2 | ×1 |
x - 6y = -5 | ×2 |
2x − 3y = 2
2x - 12y = -10
____________--
9y = 12
y = 12/9
y = 4/3
2x − 3y = 2
2x - 3(4/3) = 2
2x - 4 = 2
2x = 2 + 4
2x = 6
x = 6/3
x = 2
The measure of an angle formed by two tangent lines intersecting at a point outside the circle is equal to one-half their intercepted arcs.
XYZ = 1/2(XSZ - XZ)
XYZ = 1/2 (220 - 140)
XYZ = 1/2 (80)
XYZ = 40
The measure of angle XYZ is 40 degrees.
Hope this helps =)
Ah well this would look like 2(30) + 30 = 90 aka 2L + W = 90
