Solve the system of equations by the addition method.<br> 1 - 3x = -5y - 8<br> 6x<br> 3y = -5
Advocard [28]

-3x = -5y -8~~~....(i) \\\\6x -3y = -5 ~~......(ii)\\\\\text{Multiply  equation (i) by 2 and do (i) + (ii):}\\\\2 \cdot (-3x) + 6x  -3y = 2(-5y-8)  + (-5)\\\\\implies -6x +6x -3y = -10y -16 -5 \\\\\implies -3y   = -10y -21\\\\\implies -3y +10y =-21\\\\\implies 7y = -21 \\\\\implies y = -\dfrac{21} 7 = -3\\\\\text{Substitute}~y =-3~ \text{in equation (ii):} \\\\6x - 3(-3) = -5\\\\\implies 6x +9  = -5\\\\\implies 6x = -5 -9 = -14\\\\\implies x = -\dfrac{14}6 = - \dfrac{7}3\\

\text{Hence}~ (x,y) = \left(-\dfrac 73, -3 \right)

Inessa [10]

Answer:

13.05cm^2

Step-by-step explanation:

Area of a triangle is given a half the product of base by the perpendicular height:

A=0.5bh

Given h=9cm, and b=2.9cm, the area is calculated as:

A=0.5bh\\\\A=0.5\times 2.9cm \times 9cm\\\\A=13.05cm^2\\

Hence, area of the triangle is 13.05 sq cm

brett shaded4/8 of a sheet of notebook paper.Aisha says he shaded 1/2 of the paper. Are the two fractions equivalent?
tankabanditka [31]
Yes, the two fractions are equivalent because you can find a greatest common factor in both the numbers.  In this case, the GCF is 4 because it goes into both 4 and 8.  Then, you divide each part of the fraction by 4.  Then, you get the answer 1/2.  Therefore, the fractions are equivalent.
