Answer: 35
Step-by-step explanation:
Let the number of nickels be x
Then the number of dimes, using
ONE PART = TOTAL MINUS OTHER PART,
is 35-x. ( hope this helps have a good day/night :) )
Answer:x=31
Step-by-step explanation:
the total degrees is 360 which can be cut into 2*(3x-5) + 2*(2x+30).
3x-5 +2x+30=180
5x+25=180
5x=155
x=31
to check your answer do 2*((3*31)-5) + 2*((2*31)+30) which equals 360
must equal −40

Answer:
Step 1 Given. 4·0=0
Step 2 Substitute. Any number plus its opposite is zero. 4(10+-10)=0
Step 3 Use the distributive property. 4·10+4·-10=0
Step 4 Multiply. 40+4·-10=0
Step 5 Subtract 40 from both sides. 4·-10=0-40
Step 5 Simplify to solve for 4·-10. 4·-10=-40
Answer:
√55
Step-by-step explanation:
Notice that the small triangle in the bottom corner shares an angle with the overall triangle. Also, they are both right triangles. Therefore, they are similar triangles.
Notice that the large triangle at the top shares an angle with the overall triangle and is also a right triangle. Therefore it is also similar to the overall triangle and the smaller triangle.
Writing a proportion between the small and large triangles:
y / 11 = 5 / y
y² = 55
y = √55
Answer:
d=3/5
Step-by-step explanation:
3 ( 4d + 1 ) - 9d = 6 - 2d
12d + 3 - 9d = 6 - 2d
12d - 9d + 2d = 6 - 3
5d = 3
d = 3/5
d = 0.6
