your answer will be 2.5833 hope this helps!!!!
Step-by-step explanation:
There are 16 girls and 12 boys which means the ratio of number of girls to the numbers of boys in her class is 16:12 and 4:3 when simplified.
<span>8(x-3.7)
To find this, you must first use the distributive property.
8 • x = 8x
8 • -3.7 = -29.6
</span>8(x-3.7) = 8x - 29.6
Since there is no way to completely solve this since it's only an expression and not an equation, this is in simplest form.
You can simplify expressions by simplifying parentheses by using the distributive property and combing like terms.
Combining like terms is the process of adding up numbers with the same variable(s) and exponent. If a term does not have an exponent then an exponent of 1 is implied.
There is no parentheses in the expression 3a + 7 - a - 7
But, there are like terms in the expression.
Which are the like terms?
3a and a are both like terms. They both have the same variables and they both have the same exponent.
7 and -7 are like terms, too.
3a + 7 - a - 7
2a
So, 2a is the simplified version.
Answer:
1). y= -5+3x
2). y= -2x-13
3). y= -6x+2
4). y= -x+4
5). y≈ 0.57x
6). y=2x-9
7). Equation incomplete
8). y=3x+23
Step-by-step explanation:
1).
3x-y=5
<em>Subtract 3x from both sides</em>
-y=5-3x
<em>Multiply both sides by -1</em>
y= -5+3x
2).
y+7= -2(x+3)
y+7= -2x-6
<em>Subtract 7 from both sides</em>
y= -2x-13
3).
y= -10-6(x-2)
y= -10-6x+12
y= -6x+2
4).
3x=12-3y
<em>Add 3y to both sides</em>
3x+3y=12
<em>Subtract 3x from both sides</em>
3y=12-3x
<em>Divide both sides by 3</em>
y= -x+4
5).
-4x-7y=0
<em>Add 4x to both sides</em>
-7y= -4x+0
<em>Multiply both sides by -1</em>
7y= 4x
<em>Divide both sides by 7</em>
y≈ 0.57x
6).
4x-2y=18
<em>Subtract 4x from both sides</em>
-2y= -4x+18
<em>Multiply both sides by -1</em>
2y=4x-18
<em>Divide both sides by 2</em>
y=2x-9
7).
y= 5-
Equation is incomplete.
8).
y-2=3(x+7)
y-2=3x+21
<em>Add 2 to both sides</em>
y=3x+23
