Write a system of equations and solve.
x + y = 10
5x + 10y = 90
Multiply and combine equations
-5x - 5y = -50
5x + 10y = 90
------------------
5y = 40
y = 8
x = 2
There are 2 nickels and 8 dimes in the jar. Hope this helps! :)

1: Assuming this line is linear, the first thing to do is find the slope.
The slope formula is

, so in this case, it is

, which comes to

. Then, use your slope and one of the points given to write the point-slope formula of the linear equation, and then written in standard form:
y=

x-

.
2. Use the same process as in question 1 to find:
y=-7x+11
The first one is D. Y=-3+8x
The second one is G. -3/2x=y+2
In the binomial expansion (2x + 3)^5 , there are 6 terms.
According to the question, given that
Binomial expansion (2x + 3)^5
Number of terms in a binomial expansion of (x + y)^n is
N = n + 1 words in total
In the binomial expansion (2x + 3)^5
n = 5
N = 5 + 1 = 6
Therefore, In Binomial expansion (2x + 3)^5 there are 6 terms.
The algebraic expression (x + y)n can be expanded according to the binomial theorem, which represents it as a sum of terms using separate exponents of the variables x and y. Each word in a binomial expansion has a coefficient, which is a numerical value.
The formula for expanding the exponential power of a binomial expression is provided by the binomial theorem, sometimes referred to as the binomial expansion. The following is the binomial expansion of (x + y)n using the binomial theorem:
